The men's toilets in the international arrivals were embarrassing to say the least. They looked as if they have been built in some kind of temporary hut? Freezing cold and stinking of urine. Are they actually regularly cleaned? If so, then someone needs to take a serious look at the Cleaning staff performance or the plumbing, as something is definitely not working properly. The car parking facilities are inadequate. Surely another multi storey car park is required. The cost for parking for 1-2 hours is an absolute rip off. The layout of the international check in area is a joke. Hardly any space for queuing and people trying to proceed with their luggage and trolleys to different parts of the airport. The immigration part of the international departures was the worst I've ever seen at any international airport I've been to. Very cramped with the staff shouting at the top of their voices telling customers what to do. One of your staff should try queuing and passing through this area as a customer, as I think u would be quite surprised with the operation. My wife accidentally forgot to lift her tray off the conveyor belt after her hand luggage had been scanned, and was told very aggressively by a male member of staff to get her tray off the conveyor belt. I approached the gentleman and told him to calm down. His aggressive response was "what did you say to me, do you have a problem"? I just walked away and wouldn't rise to his confrontational attitude. Overall a very disappointing experience. The next time I visit Edinburgh, I will fly with Emirates and will arrive at Glasgow airport.
