I know it is not required to tip the club counselors or the sitters at Flounders but have read that it is a nice gesture. My question is how do tip when there is more then one counselor or sitter? When we would go to pick up DD at the club there would be 1-2 people at the desk, and many counselors at the club. Same at Flounders, there would be 3-4 people working when we would go to pick DS up. How do you know who to tip?
