Subway lottery
When you go to Subway and tell the people making your sandwich to "Surprise me". The results can vary from delicious and unique to disgusting and nightmarish.
"I'm sick of the same, boring sandwich. Let's play the Subway lottery!"
"I just got a cucumber carrot jalapeno seafood sandwich with sweet onion sauce, vinegar & mayo. Looks like I just lost the Subway lottery."
