Once, in BK I had just purchased a large soda, and walking away it toppled off the tray and spilled everywhere. Naturally, I asked for a mop, since it was my damn fault. But they were so impressed I asked that they mopped up and gave me another free soda as a replacement. I always eat in BK now if fast food is required.
Conversely I was in a KFC, and ordered chicken wings. The wings arrived and they were red raw, so naturally I asked for a refund and some properly cooked wings. I was told (not without sympathy) that the manager was an +donkey fundament+ and would insist on coming out to the restaurant in person before a refund could be given. In those days I was quiet and reserved, and waited patiently using my zen ninja skills. These days I'd have yelled at him. Cretin.
The moral of the story is: don't take poisoned apples from wizened old crones. What is wrong with you people? What kind of irrestible sales gimmick do you think a crone is, anyhow?
