Yeah, typically with my phone number on it. Once got a text from one of the waitress's boyfriend asking me where I live, I was in Idaho on the time on vacation, and was heading home to Texas the day he replied. Told him to take his GF's tip money /prostitution money she probably gets on the side and buy a plane ticket to Texas and come kick my ass, then said "Peace out partner" and blocked his number. Made my day.
