When I frequented small cafés before the epidemic lockdown, it was typical in San Francisco to get frequent impatient door-knockers.

Part of the problem is the lack of publicly available restroom facilities. Shopping malls often might have two restroom pairs, usually at the food court and by the movie theater, and then one each at thr major department stores, typically hidden by the changing rooms.

I cannot say how this compares to other towns or other nations, but designing public lots in The Sims 2, I quickly learned to make sure there were facilities a short walk from everywhere. (Also skip the sinks and install showers, since sims dress and undress with a quick spin)
