The museum is very nice but I had a very bad experience in the shop with the guy who was there. There was a game displayed in the shop with a price and when I went to pay, he said the price was different. I pointed out at the price on display but, instead of apologizing, he started to behave in a very rude manner. I would not mind to pay more for the item, but I do not accept such a behaviour if I am a client in a shop. Persons like that should not work in sales. He definitely had no manners. I will write a formal complain to the museum.
