A while back I went into a restaurant and ordered a sandwich. To my dismay when the sandwich came, the lettuce was brown and wilted. When I asked the waiter to replace the lettuce he told me that was all the lettuce they had.
It occurred to me they had several options before serving the brown wilted lettuce. They could have simply told me they were out of lettuce and offered a substitute and while I would have been disappointed, I would not have been nearly as disappointed as I was. The fact was, rather than admit they had made an ordering mistake and were not prepared for their day, they had simply tried to serve a sub-standard product and hope I would not notice. I no longer eat at that restaurant.
