Don't get me wrong, the tour is great and the tour...

Don't get me wrong, the tour is great and the tour guides are amazing. However, at the end I tried to buy a sign. It was croweded and I couldn't see the register, so I went up to some employees to ask them where I could check out. I was polite, said, "Excuse me" and waited for them to help me. They didn't listen and continued talking to each other. I said it again, and they looked at me, and then proceeded to talk to each other. Tour guides and tours themselves are great, but some employees are just rude.
