I hope he reads this. After a bunch of expensive equipment disappeared under his watch we fired him. The day after, standing around the coffee room I mentioned. "Too bad they fired him, he owed me 50". Three other people suddenly said, "He owed us 50 also." It turned out the same story for everyone. He borrowed 100 and returned 50. (note: some of my best friends are sysadmins so don't get me wrong)
