We were testing out an interactive part of the exhibit, and it was very faintly written that the machine was out of service. I tested it and the machine actually worked, but then my son tested it and was told by the staff that it was out of service and told my friend, "Can you read?" In a very rude and condescending tone. We wanted to try out the free drawing service but after such an attitude like that, we left immediately. My son has bad eyesight as it is, and to be treated like that is completely unacceptable. DO NOT RECOMMEND. Better and nicer staff would improve this place. read more
