Costco Vs. Sams Club

So tonight we went to Sams Club, you know to stock up on Snicker Ice Cream Bars..and the nice man was scanning our items before it was our turn at the register. He was talking to Oliver about stuff and asking him if he liked to come to Sams Club. Oliver stopped to think and said...."I like Costco." The guy laughed and said, "well Costco is better at some things, but I think we're pretty good too." Oliver shrugged his shoulders and then changed the subject. Made us laugh.
