I was brainstorming with my friend Amy, and we came up with a bunch more:

• People either think what you do is awesome or scratch their head and walk away
• Nobody expects to pay for it
• Involves lots of berating
• Nobody gets the dress code
• You always have to beat the client into submission

Also, I had to look up the plural of “dominatrix”. There’s two theories, and honestly the math minor in me wanted to go with “dominatricies” but this is the more colloquial answer.
