Haha... Something like this happened to me as well. It probably wasn't THIS bad. I went to buy a Cam as well (only I was deciding between Canon D1000 and Nikon D60 ;) and was facing the same problem. They just didn't give a damn. So before I got to the insulting part I went next door where they (I think) had watched the scene and were treating me quite alright.

I ended up buying the D1000 but I'll never buy anything like this again in HK. It had serious resentments for a long time towards HK after this. Then again: I probably went to the worst place ever to do it: Tsim Sha Tsui a few meters north of Chungking Mansion. First day in HK and I just didn't know better...
