This sometimes works in your favour. Went to a gig in London 12 years ago and as I was skint, I had to book a room in student digs through late rooms. £70, had to pay a 10% deposit when booking and pay the rest when checking out. As my bus back to Glasgow was at 8am I checked out when only security was at reception and they couldn’t take my money, and I wasn’t chased up for it after. Two nights in London for £7 - result
