So I was in a very stereotypically chauvinist situation last week: Two colleagues and I took a customer (all 4 of us men) out for lunch after(/as part of) a sales call. After the waitress left to put in our orders, the customer made a pre-excuse and then joked something like
well that’s definitely putting a rack on a shelf.
I don’t remember how I reacted. I’m also not sure what I wish I had said.
