This receipt tells a story. It was printed well after 1am, and it belongs to a customer who came in and ordered nothing but one single steak. As a waiter or waitress, you'd probably ask yourself what that customer's deal was. We'd probably still avoid writing this in their receipt, though.
There are two ways this description could have got where it is. Either the customer phoned ahead and gave this as their name, or the staff thought it was an appropriate description of them. If it was, we doubt they noticed it.
