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 |
| 23 |
units. They "couldn't get in". One guy says, "I'm on the internet, don't know |
| 24 |
what's wrong". The other guy says, "It's _them_ ..." So they couldn't even |
| 25 |
tell me the price of the filters, or if they had them. So one guy walks in the |
| 26 |
back and does it the "old fashioned way" -- he just looks. (Reminds me a bit |
| 27 |
of sneakernet.) By the time he gets back, and tries again, "Hey, it's working |
| 28 |
now ... quick!" |
