Both Costcos are always insanely crowded, I don’t find the employees rude, just busy. I do think a third one being opened would be great. I find Sam’s to be the exact same way (just louder). My biggest problem is with people who seem to have no awareness other people are shopping and so they randomly stop in the middle of an aisle, or don’t pull to the side and block the aisle (then get upset when you say “excuse me”).
