You just said that iced coffee was enough to let you know someone wasn’t serious about client expectations and that you still work at a place that requires a suit and tie on occasion. I’ve never worked somewhere that had a dress code, even one that didn’t apply all the time, that didn’t mention hair.
Regardless, I find it hard to square the idea that iced coffee wouldn’t fly but an Afro would. But maybe I just live around a lot of racist people.
