Not unfamiliar hydeaway - members from the early days of CBF will remember the unnamed hotel and unnamed Brit in this - a British guy we knew had a favourite hotel and although he had his own place in Calis, spent a lot of time at their hotel bar (nothing wrong with that of course

) - anyway, as a favour he picked up a litre of Bacardi at the airport for them, as it is very expensive to buy in Turkey. His favourite tipple was also Bacardi. During his stay he had many Bacardi & cokes at this hotel bar, almost finishing the bottle single handed.
Imagine his surprise at the end of his holiday when he went to the hotel and asked for his bar bill - only to find he had been charged, full price, for each and every one.
