Beautiful art, but they need some help !
The attitude of the staff was RUDE, RUDE, RUDE ! They could learn something from theme parks that know how to handle crowds and treat them properly and nicely.
In addition, the facilities need help. Before you can use the restrooms, you MUST show a purchased ticket. Once inside there are no toilet seats, no bathroom tissue, no soap and towel dispensers that don't work. Plus, several of the stall doors have been kicked in.
For a museum that is sold out in advance and bringing in money, they need some up-grades and some staff training.
