"But I left the door unlocked.."

This is not my story, but was told to me by a coworker about an hour ago:

So a while ago the maintenance crew put in a wall and a metal / glass sliding door to turn one big room into two smaller rooms. As a result, the second room doesn't get much in the way of wifi signal. To alleviate the problem until a second access point was installed, we opened the sliding door.

So the other day one of the people who work in "new" room complained about the wifi signal again. Coworker wanders down there and finds the sliding door was closed again. He says "yeah the wifi sucks because you closed the door", to which the person replied "..but I left it unlocked"
