We went out for a walk tonight and popped into local shop for an ice-cream. It has a small cafe during the day but only serves take-away after 5pm. She asked to use the loo, they said no, it was shut. She said her DD had used it before, and the owner said that they always let small children go, but not adults. Friend is pissed off and now boycotting the shop.
I think they were being very reasonable.
