I was going to leave a stealer review. The place was beautiful with a emphasis on African American mathematicians and pilots. An amazing learning experience for my son, right down to the IMAX theater. HOWEVER, upon leaving I figured let me spend my hard earned money on memorabilia from the gift shop. Not sure who the older Caucasian man was but he was screaming at, what I was told was a manager. That is completely unprofessional. I tried to mind my business up until the moment my son asked why the lady was being yelled at. I mean berated. Did he not know the place was open and full of patrons? That is unacceptable and disgusting . Absolutely disgusting and rude behavior. I will not spend another red cent until your manager/director/ whomever learns to handle things better. Such a poor way to end a treat. Keep your 10.00 robot arm.
