I call bullshit.
I don't believe for a moment that 200 moms in here do the "eat what you got or go hungry" method 100% of the time. And when I pay to send my child to camp I expect that I'm paying for my child to be cared for and allowed a fun time. The counselor could have used it as a social opportunity and suggested he find someone to trade with, or told him to wait until the end and see what was left to teach patience, she could have even explained he had to take what he got and just moved on for him to work out (because he would have) I just don't see where it's her job to punish him. Seemed like an asshole thing to do IMO.
