Yeah well, when I go to a viewing, the landlord/lady always offers me a tea or coffee and I feel rude not to accept their offer! Which is all fine, but then you leave the house with a full bladder and well, it seems rude to ask to use their toilet.
And as it happened, I had two viewings today and therefore needed two toilet trips.
FYI: the services in question were the BP services on the junction of the A10 and the A142, just outside Ely.
