So fun fact, I actually had this happen to me at an office job x33 like I had a designated bathroom that had a single occupancy limit I used to change myself on breaks cuz I'm unpottytrained and one day, I came in for a change and I saw that EXACT👏SAME👏SIGN on one of the industrial sized trash cans and I can't describe the emotions I felt when I first saw it ... mostly shock. Thankfully no one ever walked in on me during the process, or I'd have had to quit right then and there out of sheer embarrassment.
Also her response to the potty is identical to me as well cuz I have had a phobia of toilets for years (not a joke). I've never directly related so much to a protagonist in one of these stories x33 can't wait to see how far it goes!!
