Sneezing
This just sucks, now and forever his Costco membership card will feature this terrible picture of his face while sneezing. We are sure that this gets a big laugh each and every time he takes a trip to Costco. Imagine having to relive the moment the cashier chuckles and asks you about it, over and over again.
We do not want to know what that is like, we would rather file an official complaint and get this picture redone. We would keep it at home for a good laugh every now and then, but at the store sometimes we just want to simply handle our business and leave.
