Sometimes a thing so offends your sensibilities you just to do someting!
Why, just the other day, I was leaving a shopping center when I noticed a switchgear door open. It was hard to miss- it stuck out into the traffic lane! Maybe too hard to miss- some one had "tapped" it just had enough to bend the rod that held it in the 'open' position. A moment with a pair of pliers, and the door was once again closed- securely this time.
