I remember a lot of the other waiters getting overly upset with the grillers when they made the occasional mistake with an order. It never bothered me though. I was almost always guaranteed an extra 5% tip when there was a mistake, because I got to show how well I handled it. Damage recovery is one of the very few times you get to show-off. It’s often difficult to shine when all is running as expected.
By the way, I get a child-like thrill that a post by a guy in Texas is picked up in London and embellished in Johannesburg.
