Fish Sandwich vs. Double Cheeseburger

I learned something new today at a local fast food restaurant. Apparently, the words “fish sandwich” can easily be heard as “double cheeseburger”. I ordered a fish sandwich through the drive-through window, and I happened to check my bag to see what I had. Lo and behold, there was a double cheeseburger. When I went back to the window, the lady said “I’m sorry, I thought you ordered a double-cheeseburger.” They were out of fish, so I had to get a baked potato.
