"Vianne once delivered a Starbucks order to one well-known celebrity. Starbucks has changed since mobile ordering, but at the time, 'you had to go in, order the drinks, pay, and then you wait for the drinks [to] deliver to the person. I was so upset because he didn’t give me a tip. What the hell, dude! Even if it’s just one dollar, give something. Don’t just not tip.'" - Saru Jayaraman
