I have to call places before I visit them. I never know if I should say “I’m fat” (a term I embrace, as it’s technically correct and not a derogatory word) or if I should go for something less tension-provoking like “larger person” or “plus-sized”.
Most of the time, I just go for: “I’m calling because I would love to come and see a show at your venue and I was wondering if you could let me know the sizing of your seats? It’s just that I need to know if my butt can fit into them.”
