Somewhat tangential, a friend of mine waited tables at a restaurant in NYC and was offered the sole work on a table of 30 diners. He jumped at it. The host was Pete Seeger, the famous folk singer.
What he didn’t know was that Seeger was a communist who NEVER tipped. Marx wrote a paper on the evils of tipping. The other wait people knew this from past experience and gave my friend the Seeger job, knowing he would be working for below minimum wage that night.
I have a friend who once waited on Sean Hannity and a large group at a high end place in Long Island. Hannity is known as a 100% tipper. His tip equalized the $5000 bill.
That said, I’m sick of the tip everyone mentality. If all they do is hand me a bag of food, they are already earning their money. My tip is $0.00
