Ok, now I have friends that do bartending as well as those that work at restaurants. I honestly feel you should tip if the service is satisfactory. Of course, if the service is completely whack, that's a different story.
If you order a 10 dollar drink at the club, you should at least tip 2 dollars. People fail to realize that bartenders make less than minimum wage. The bulk of the pay is based on the service. So if a bartender goes out their way, makes you excellent drinks, and gets you where you need to be..TIP! Plain and simple. If you go to a club or a bar, and don't want to tip for your drinks - then don't buy drinks! You might as well just ask for tap water all night long!
Honestly, even if the drinks are half off..I still pay the same kind of tip. I've noticed that in life, the more you give, the more you get. That's the honest truth. I remember I was tipping this one bartender really well and the cat was really happy and thanked me. I mean, he was makin the drinks just how i like them..smooth but strong! Can't go wrong! I mean, if someone was making my food, or drink...I'd tip them because you never know what might happen if you get that person again..hahahaha. Hear what Mr. Skyy John has to say!!
