LMAO I mean the DP jokes, even back then (when perhaps DP wasn't so well known, this was like 98), were common. DP dough was really just white trash odd flavored calzones but they are kind of amazing at 3AM.
My family member has tipped people to the degree they come back out and ask if it's a mistake, then they make a HUGE deal out of it (cuz he really overdoes it, 150% tip on a couple hundred dollar meal), and I feel like it was at least PART of his goal. I've dropped some tip bombs in my day for the right person but I just write it down or drop the bill, and leave.
