order amnesia 

A condition that afflicts restaurant patrons after they order their meals; the server brings the food to the table and nobody can remember what they ordered, staring blankly at the server as he calls out the name of the dish burning his hand.

Server: Wow, that table had a bad case of order amnesia, I think I called out, "steak fajitas for two", at least a dozen times!
