The worst that can happen

"What's the worst thing that can happen?"
A frequently asked question to put things in perspective. In the weekly newsletter from the big gym, alias my employer, one can read that the worst thing that can possibly happen is a cancelled class. A class where the group instructor doesn't turn up and there is no stand-in or other solution. Apparently it happend once in the last semester.

Compared to the answer one may get from a chef (cooking causing food poisoning?), a taxi driver (bad driving causing serious delays leading to missed plane?) or a doctor (wrong treatment leading to deteriorating condition?), the impact of a cancelled class seems petit. But I'm sure the instructor in question feels like a real failure considering how many times the mistake has been communicated to the whole group of instructors as the worst thing that can ever happen... Building company culture by promoting the good examples and name and shame the bad ones.
