I'm a 6'4" imposing looking dude, even though I'm a pacifist. I think if any of my employers ever tried yelling at me, I'd look at them like scrappy doo was telling me to put up my dukes.
A mix of amused and confused as to why they believe I care that they're angry about anything, let alone that that I'd do anything different in response to an adult having a tantrum. Like dude/dudette, I'm here to sell my labor, either let me work and pay me, or tell me you won't pay me anymore so I can leave immediately and forget your name in an hour.
