Everyone should know this, even if they're not on my myspace.
First thing you do when you walk into a bar should be to make a beeline for the rail and try to get the bartender's attention using any means necessary, the way you would for your dog. Whistle, clap, pound on the bar, anything you can think of. Once the bartender gets the hint that you ARE the most important person in the bar and comes over to worship you and shower you with attention, you should then act like you have no idea what you like to drink, because you've NEVER been to a bar before.
Ordering your drink should consist of a few separate steps. First, ask the bartender what's "good today." Every bar ships in their liquor and kegs fresh from the Atlantic every morning and each batch will taste different. Second, make sure to ask what's on tap, because the tap handles in front of your face DO NOT represent what they really have. If two or more beers on tap have similar names, such as Labatt Blue and Blue Moon, make sure to order one in the most vague possible manner, such as "I'll have a Blue." If they ask you which one you mean, they're clearly a retard. Third, make sure to take as much time as possible asking your party what they want to drink, because they're incapable of ordering for themselves. Your party should consist of at least 5 people who also have never had a drink in their lives and don't know what they like. Ask the bartender a few times what they have that's "fruity" for your girlfriend. Make up a drink that no one has ever heard of with 6 different things in it and give it a stupid name, like a "fizzy purple turtle eater" and scoff when the bartender has no idea what you're talking about. Order one, along with 3 built shots, 2 shaken ones (make sure the shaken ones are different kinds so they have to do it twice with two different shakers), and one cream shot, just to muck up their sink. When they're done making all your nancy shots, make sure to ask for one more. DO NOT have your money ready by the time they're done making your 7-minute round of drinks. Nobody has ever had to pay for drinks in the history of alcohol. If you're starting a tab, act surprised that they want a credit card. They've known you for an entire 7 minutes at this point and should trust you to not walk out on it. Actually, they should trust you with their life too. They should probably just let you get behind the bar and make your own drinks. You're a very trustworthy person.
When you have your drinks, please refrain from removing yourself from the rail area. No one else in the bar is trying to order a drink, ever. It's all about you. Make sure for the rest of your time there to order your drinks one at a time, to make sure the bartender is constantly busy with you and your party. But don't tell them when you need a drink -- bartenders are mind readers and should know when you want another nancy-ass pineapple upside down cake or vanilla raspberry truffle pom pom bomb. While they're waiting on you, make it a point to ask them about all of their tattoos, because they definitely want to tell you the story behind every single one of them and why they got them. Once a bartender has served you a drink, they're immediately your best friend and should tell you everything about them, including how much they make and how their weekend was. If they don't want to discuss it, they're being rude. Oh, and also ask for lots and lots of peanuts. Bartenders always make lots of money on peanuts.
When you're ready to leave, if you have a tab, make sure to ask for a copy of your tab, and argue it. You are obviously more aware of what you and your 15 friends drank after 5 shots and 10 beers than the sober bartender. If you're paying cash, never pay the entire thing yourself and get money from your friends. Everyone in your party who is scattered throughout the room should come up individually with their wadded up $1's and nickels and pay a portion of it. NEVER, EVER tip. Tipping is a sign of weakness. A bartender will NEVER alter their level of service to you upon your next visit based on your tip. Ever.
On your way out, please leave all of your old Dunkin Donuts receipts and gum wrappers on your table. If you could, also put some chewed up gum in the ashtrays. It gives the bartender something to do while they close. While you're at it, don't even use the ashtray for your ashes. Use a glass. Preferably one that can't be cleaned without being run through the glass cleaner sink, which will have to be changed after doing so. A bartender considers it a sign of respect to leave 3 pennies and a nickel on the table when you leave as well. And please, leave all your peanut shells on top of it.
