Sororitygirl2! Good to see you again
I won't go out with those cheap people again or make them get seperate checks.
Last time i went out with a fraternity brother and his sorority girl friend it cost me 30 dollars plus to cover their "oops didn't bring enough money" as well as the fact that they wouldn't have tipped anyway. I know them. Keep in mind they both work.
I tend to overtip. 40-50 percent is not uncommon for me at all. And I despise people that give the appearance of quibbling. You can quibble, but don't let it show lol.
There is one place that I go to regularly where 50% would be the norm but I have gone as high as a 100% before because I will sometimes get generous freebies, like comp drinks and food.
In any restaraunt I go to where I get recognized, I get incredible service.
