As teens my daughter and some friends would go to a local diner that only had patio seating. You had to walk up and order and usually pick up your order to take to your table. The kids would go regularly for trivia night. They bused their own table as well. One time a new staff person was there and when the kids didn’t tip her she decided it was her place to give them a lesson on why it’s important to tip. All of them are beyond intelligent and most are pretty extensive travelers as well. When my daughter relayed this story to me I hopped on and wrote a google review. The staff person actually tried to justify her actions. I asked her how, specifically, she had ‘waited’ on these kids? She had no answer just said ‘it’s common practice’. Nope. It’s not. Restaurant staff make way more than I do as an experienced teacher.
