Is it morally wrong to use a fast food chains toilet without buying food there?
Of course it’s not ‘morally wrong’ McDonalds in Oxford St has been a godsend to me and my kids at times! Starbucks has a tendency to lock it’s toilets and you have to get a code for the door from a member of staff, I’m sure other outlets would do the same if it really was a problem for them. When I was a kid my dad would take us to a pub if we were desperate for the toilet. I think these places sort of expect that the general public use their facilities, and so long as they don’t get vandalised they’re normally ok about it.
