I entered at the lower below street level entrance where pipes were both on display and for sale. the owner apparently doesn't understand english and when I asked him if I could take photos he responded with a cheerful "yes! every things for sale" seemed simple to me (there were no signs saying photos weren't allowed). a few minutes later however as I was taking a picture he shouted: "that's extremely rude!" he then came around the counter, slapped me causing me to crash back into a display, and then started kicking me while at the same time he tried to grab my iphone. I have never been so startled in my life. A simple - "I think you must have misunderstood, we don't allow photos" would have sufficed. Physical abuse is unacceptable in my opinion no matter what he had been smoking.
