People are aware toilets particularly at the moment are in limited supply. A friend and I were out yesterday and she was drinking a bottle of coke which is obviously known to make you need the toilet due to caffeine. She then inevitably needed the loo she went into a coffee and she said how desperately in need she was. Aibu to think that unless there is medical conditions most people know they need the toilet for a while before they are urgently need to go. She was then annoyed that they refused her due to being a customer.
