Lost in Mentaltown

A man comes in around midnight and asks what town he's in. I said "This is Mentaltown". He says "Really? I've been wandering around for several hours trying to figure out where I am" I asked him where he was heading and he named a town about 20 miles away so I asked him if he wanted to use our phone to call a cab, he said "No I've got the money but I'm a firm believer in what doesn't kill you makes you stronger" I am too, but I'm not going to walk 20 miles somewhere I don't have directions to, in 20 degree weather. I asked the guy if he was sure, and he said yeah and left.

A few hours later he comes back to buy some Red Bull. I asked him how his travels were and he said "I got half way there and decided to come back"
