Just when I thought all the food on the DDP was crap I had lunch at Tuskers in AK. The food there is great and I would recommend it to anyone. Initially I got the receipt that showed zero and thought ok, it's a buffet and they're not looking for a tip, but then the waitress brought the "real bill" with that 18 and 20 percent suggested tip.
I usually just leave around 10% if it is a buffet and decided that is what I would leave there (it actually came out to about 12%). I told the waitress what I left and why and she didn't seem very appreciative. Should I have left 20%?
