jamtalterious johnson, i can tell i'd never leave you a tip.   i view tips (in the u.s.) as a curtsy and have only ever based it on the waiter/waitress themselves. if they're ugly, i'll toss them a bone (10% min). if they're pretty, i'll base it exclusively on social interactions and or energy. every now and then, i'll google the closest restaurant out side the city limits (while on work trip/vacation) just to see if there's anything of interest. point being, the remote ones have always had great people to converse with, so i tip up to 30% (especially on company card). thankfully, i've only ever had two rude waiters, so i can't say it's very common. in the city however, the times where the waiter/waitress only brought food and took orders, i give a hard pass. especially, if it took forever. regardless of the delays, i will not tip if i had to wait pass the allocated time. sure, i'll get paid for it, but at some point it become my time and it's flat out unacceptable.  i see it the same as tipping at a self checkout. i'm not saying i expect great energy, but if you're a ghost and only bring the beverages to the table, then i see zero point in tipping. i could do that at home, but since i'm not hosting a meeting in another country, that's that.
