In a town built on tips, I can tell you that tipping will get you a long way if you plan to repeat buisness with said people and expect good service or these people to go out of their way to help you above and beyond the call of duty.
Although many people feel pressured or obligated to tip, the SMART people know that greasing palms is a tried an true way of not only making yourself appear classy (even if that's not the case) and make a connection that might be worth more then the extra money you threw on the table. I can't tell you how many wait staff members, valet drivers, bartenders, cab drivers and other attendants will literally break their necks to help you if you're in a delema of some kind that has absolutely nothing to do with their job. They'll hook you up with attractive girls, they'll get you into night clubs free, they'll get you to the airport before your flight departs, they'll give you free desert or free drinks, they'll serve you before other people when it's crowded, they'll get another staff members number for you when you're too chicken, they'll tell you what the best strip clubs are in town and give you the name of tho hottest stripper there getting you a free lapdance...the list goes on and on and you're only out a few extra dollars.
Now think of the converse if you don't tip. They serve you last, their service to you is far, they take the LONG way to the airport, they send you to GAY nightclubs, they spit in your food when you come back to their restarunt for a second time, they ignore you completely when you sit at the bar, they mess up your bill and have you paying extra, they back some other guy who does tip and is obviously drunk when they pick a fight with you getting you kicked out of the bar etc etc.
I know it's a glum reality but really the advantages of tipping are numerous other then the fact that you're making someone happy just by showing them that you're gratious for their service. A lot of places add gratuity to your checks anyway taking that burden off your shoulders so you pay one way or the other. The downsides of not tipping are really the deal maker though. Nobody likes a cheapskate, i mean come on it's only a few dollars here and there. Are you really gonna miss it all that much? I'm industry so it's really easy for me to say but honestly I've gone out sooo much in this town and gotten more then my share of free drinks and VIP treatment because of tipping. I've gotten 500 dollar bottle service at premire nightclubs FOR FREE and tipped my waitress 100 dollars. For those of you struggling with the math I SAVED 400 BUCKS BECAUSE I TIP WELL. You really can't argue with that,
