Guns N Guys Co - Hong Kong

I went to Hong Kong for a short holiday, and decided to check out the hobby shops there that sold Airsoft guns and parts because I thought it would be cheaper than back home. At the shop, I asked one of the people whether I could see a Tokio Marui H&K USP, to my surprise, he stared at me with a really black face and said "No". He then said something in Cantonese, which I couldn't understand, so I just took the box from the shelf and the same guy looked really angry. In the end I bought the only the USP and left quickly, though I really wanted to look around some more. I was, and still am, extremely upset with the customer service of this shop. The product quality was satisfactory, and the price reasonable, the thing that really put me off was the service.
