No idea why people go to these "membership" box stores.  I can't spend more than 5 minutes there and find nothing worth buying.
I have friends who think these places are the bee's knees.  

Who wants to wander around a windowless warehouse all morning to buy 5 litre ketchup bottles?  And what's with the inspectors at the door to check your membership? Like it's a privilege to spend your money there.

Places like these have impersonal, rude service.  Why would the writer expect otherwise?
