Shocking service and experience

First I was rudely and unprofessional approach by a airport employee that I am in the wrong queue. Only to be told 20 sec later that I could join now the queue I was in before. Than at the exit passport control was ONE (1) of 14 manned, which resulted in a queue spanning nearly to the security checkpoint and a waiting time of more than 50min!! This happened at C. T. Int. apparently the best of our international airports. I do not want to know how the rest is run. Shocking service and experience!
