They said I wasn't in any trouble, they weren't interested in me, but we're trying to determine if the place was engaged in illicit activities.
They asked questions about what services I went for, what did I pay, did I pay in cash, did I make a reservation, was any offer for extras made, etc.
They asked for ID but I didn't have one on me as I had walked. They took down my name and address.
Never heard anything more about it
