I have left .02 as a tip before. At the roost I got the sliders before and ordered an odd number. My last one was like the crusties from the corner of the grill and I confronted the waiter for a replacement. He came back with it and said "we aren't going to charge you, that is the best I can do." I wasn't being unreasonable I just wanted what I ordered, so I left a 2¢ tip and wrote the message "that's the best I can do." I usually tip well over 20% so it's not that I'm cheap with the server, but this has been multiple times in a row that I received sub-par service. What really got me was when he said that's the best I can do, like it was coming out of his paycheck. I just wanted my 1/4 of a burger patty...
