Show of hands-- how many of have been at a larger group dinner and the "early leaver" (EL for short) forgets to calculate the 8% tax (leaving his tip at 12% even though 18% is calc'ed in already)? Or forgets about that second beer they ordered? Or chows on apps but doesnt contribute? Or decides they are above contributing to the birthday boy's part like everyone else (of course the bday boy *thinks* they contributed, and nobody is to rude to point out otherwise)? Or, my favorite-- all of the above!
I've been one of those check counters numberous times-- and the server should be thanking me because the server would get seriously stiffed. I am there kicking in the extra 10-20% of EL's contribution because I happen to be the type who seriously cannot stand stiffing the server. And I am NOT the wealthy one at the table (i am not usually carrying that kind of cash, coincidentally, either). So it may seem like a great suggestion, gyps808, but only because there are people like me picking up the slack of people like them.
The concept itself is rude-- leaving others to deal with what you don't want to. Because others really *enjoy* that part of the evening? Please. And if you follow this suggestion to the logical end, everyone would just drop cash and run as soon the check arrives. (I have seen this happen too. Fairly funny. Except that it adds up to a 0% tip half the time)
And to EL: don't think people aren't cursing your name at the table or appraising your cheapness on their drive home. Congratulations on freeing yourself from the rest of the social obligation these dinners necessarily present. Do the rest of us a favor, and either get a separate check or go the 'puerto rico' route (but remember drinks are taxed too, ok?). Otherwise, sit it out with the rest of us poor souls. If you MUST do the EL, then calculate your total, be generous, and THEN ADD ANOTHER 10-15% additional to that. Because after a long night and a couple drinks, i am pretty sure youve done some bad math in your head. I should know-- i've counted your contribution too many times.
As for myself, there are certain friends-of-friends i will never go to dinner with again because of pulling this stunt. My motto is, when in doubt, just bow out (of the dinner invite, that is-- not your bill!).
