@LiberalLibrarian Agreed. $18 isn't that much. I would have done the same.
I always leave a tip when I dine out. After COVID, I increased my tips and now I also tip for takeout orders.
When a person has been blessed they should pass it on. My wife and I are teachers. We didn't lose our jobs or salaries during COVID when so many did. This is one way I try to give back.
