How avoidable is this to you?

You should have told him to hide the keys in the yogurt. Nobody would look in there.

Other than that it's what NT! said. How can you not have a lock for your locker at a public gym, epsecially in this neighborhood?

Also - address on the keys? WTF? Seriously i would have pissed in this guys yogurt months ago. At least buy several of these yogurts and ask him to mix them for you.

Who the [censored] puts their ADDRESS on their KEYS!? If you are that scared of losing them put like a contact number on it. Does he write his pin number on his debit cards?
