And it happens *every* day, all over the place. Yesterday I went to Coburn's Supply to get a box of air filters for our HVAC units. They "couldn't get in". One guy says, "I'm on the internet, don't know what's wrong". The other guy says, "It's _them_ ..." So they couldn't even tell me the price of the filters, or if they had them. So one guy walks in the back and does it the "old fashioned way" -- he just looks. (Reminds me a bit of sneakernet.) By the time he gets back, and tries again, "Hey, it's working now ... quick!"
