I always check the area beforehand. There’s bathrooms that are open to public and I already make sure I check. Not sure where you’re from but I’m from a city so I know they’ll be some kind of store around or bar/restaurant I can use a bathroom. It doesn’t help my anxiety for my Ibs much but atleast I know if I’ll have a bathroom or notn

I always assume there’s gonna be some kind of bathroom I was visiting dc and there were bathrooms everywhere you just have to look and ask around
