I booked a last minute, single, holiday to Los Cristianos in Tenerife many years ago... Flight was, of course, delayed and so I pitched up at 3am, tired, hungry, irritable and a bit tearful... Receptionist threw the key at me, opened the door to the room which was grubby at best; couldn't be bothered to unpack so just threw back the covers and was about to get some shut eye when I saw a pizza box in the bed, complete with half-eaten pizza which had been used as an ashtray.... Receptionist said "we're full, no more rooms" - I yelled "get me another room NOW" - to her credit she did....
