Im thinkin of havin my 21st in vegas. i wanna get drunk as hell. what is the best way to go about doin this, my buddy says play penny slots till a waitress finds ya. once she does order a shot, this shot bein free. when she gets back tip her a 20 and ask for 5 more and a beer before she can go to someone else. tip her a 10 when she gets back and your beer will never be empty. is this a tried true method or just my buddys bullshit?
