Consider it vent art?
The thought occurred to me last week while I was waiting to get my car repaired. Stopped into a restaurant for lunch, the staff was decent in spite of it being a busy lunch rush. Set my order and .. got back not what I ordered.
Aggravating, I know, but what's a guy to do? Unalive the who- no, no, just wipe off the offenders and move on. :p
