Reminds me of the time I tried to buy Velcro at a Sears store.
From a thread in 2010:
“I can see that, but what about Velcro? Ever heard of it? Is there anybody on the continent who has never heard of it? Why yes, yes there is. The Sears employee I spoke to some years ago had no idea what it was. I even described what it looks like and sounds like when you pull it apart, and that it was used on practically every fucking thing from shoes to watchbands to wallets to jacket closures. Still had no clue. By the time the conversation was done, my wife was pulling me away because I was really losing it with this moron.”
