chefs who aren’t skinny [#2 disagrees with this– if you have a really high bar for quality food, you naturally eat less of it]
personal trainers who are buff
elderly tailors [#2 is a bit queasy about getting into demographic stereotypes… but um, she has noticed that the best phlebotomists tend to be female immigrants… that’s probably because discrimination means that in a better society they’d be doctors]
makeup artists whose own makeup looks extremely terrible (but what about hair salon people? do they cut their own hair?) (hair salon people are fine, and a good hairdresser is a jewel to be treasured)
financial planners who work for cut-rate franchises like Edward Jones (if they really knew what they were doing, they wouldn’t be working there)
Grumpeteers, can you add to the lists?
