Hypothetical #9 (Patreon)

It's almost closing time and you are dripping wet after your post-swim shower to get the worst of the chlorine smell off you. You have nothing but the swim trunks you wear, as you use the key to unlock your locker to grab your towel. You look at the locker contents in disbelief, then check the number on the key, then the locker again. They match, and you remember clearly this was the locker you put your stuff in, but that's not what's in it now. Your jeans, shirt, sneakers, and even the towel are all gone. Instead a pair of work boots with white-ish socks pushed into them, orange hi-viz trousers, a dark blue T-shirt with yellow print advertising a company you've never heard of, and a wallet in black and orange synthetic leather. You struggle to come up with a good reason for anyone to replace the contents of the locker. Almost all the other lockers would be empty at this hour.

You pick up the wallet to see who it belongs to, but what was an inconvenience just became chilling. The first thing you pull out of the wallet is your driver's license.

What do you do?
