I was there on Saturday 3rd of June and I won't come back again. I didn't like that after you buy the ticket there's a control of bags, something that you don't know neither they tell you (anyway I have no problem with it)So there's this lady that asked me to open my bag and I did so, then she introduces her hand inside and starts stirring to see what's inside. After that she yelled at me asking if she can have the bag, so I loose the bag on the table and wait for her to finish when she asks me "if I have a problem" with a menacing tone. I was shocked by her attitude and told her o didn't say anything and she responded "I see your body language and Bla Bla Bla...." and behaving nervous and defiant.
I don't know what was the problem but what I know it's that I like nice working people and I don't tolerate this kind of behaviour from somebody who's working.
