I added some products to a system on a Thursday, not remembering we added some new columns to the product definitions, and the columns were nullable. I was off Friday, so I come in Monday morning to see that ~20k customers have been getting free stuff since Thursday lunchtime. Lost something like $200k because of two nullable columns :(

Dramatically increased user satisfaction for relatively small marketing budget of $200k!

Actually, the customers get pissed off even when they get something for free, because it's just another sign of how incompetent we are :(
