Pret A Manger is a sandwich shop. Paul McCrudden is an eater of sandwiches. The relationship seems uncomplicated. It probably was, at least until Mr. McCrudden decided to log all of his activity for six weeks and then send invoices for the time he spent interacting with brands. Some might call this an interesting social experiment. Others, a dick move. All we know is that Pret A Manger decided to pay him, and the letter they sent is hilarious. Oh, and the check is nice too.
