Customer service has deteriorated significantly since my last trip in Jan. I arrived to catch KL1534 on 27 March 2012. Check-in agent said she could not tag my suitcase through to my final destination claiming that a routing of 4 flights cannot be printed on a single tag. I have taken many 4 flight journeys in the past with a single bag tag printed at the starting airport. I suspect that the real reason is that doing so involves some complication and that she just couldn't be bothered. The airside gents' toilet stank of sewage so badly it was impossible to set foot in there. Finally there was no priority boarding for Skyteam Elite members on the KLM flights: boarding was done by everyone stampeding for the gate queue as soon as the flight was called. If this airport wants to survive let alone continue charging passengers a £6 departure fee which its rivals in the region do not it needs to start running a much more professional operation.
