 in terms of what the employee did or didn't do. But this one's a doozy, and I saw this posted on social media yesterday afternoon. This guy says, I was at the airport and stopped at one of those grab-and-go food places. So I'm walking through. I grab a wrap sandwich out of the fridge. I also grab a drink out of the cooler. I walk up to the counter and put it down at checkout. The cashier's ringing me up, and then she spins around the iPad asking me how much I'd like to leave as a tip.
