@great-big-stees saidYup, been there, done that.
The number of times I have gone into the "Ladies" washrooms, by mistake.
Only once, but it was a newly refurbished pub that I knew well where the new owners had turned it into a tapas bar.
Not only had they pervesely labelled the loos as only "señores" and "señoras" with no clue to the gender there for non Spanish speakers ... but they had swapped the two rooms over.
SO not being a Spanish speaker myself (can barely mange English half the time, and this was after a few pints), I went for where the gents had been. No urinals, so took a cubicle - a woman appeared out of another cubilcle while I was washing my hands.
Actually - now that I think about it. Maybe I was in the gents and she'd come in by mistake?? Maybe the re-furb had involved removing the urinals and replacing with cubicles.
