Replying to Ski demo story

I was out in Vail last week and it was a powder day so i decided to demo some fat skis. The only fat ski they had on the mountain was the salomon gun, but it was a good price. I told the guy i wanted to demo the guns and while i was filling out the info sheet he grabbed a pair, size 165. I noticed that and i told the guy that i wanted size 175. Now i'm 5'6" but a really aggressive skier so i wanted a big powder ski which i knew i could handle and 175 wasn't that big anyway. But the guy kept insisting on giving me the smaller size, so i said,"fuck no bitch, i don't want them damn short sticks!" (not actual words) Finally i convinced the guy to give me the 175's. Is it me or should it not be so hard to get the size that i want and not what their skiing "protocol" goes by. I ended up having a great day of skiing after that and 175 was the perfect size. Has any one else ever had a problem like this with a ski shop?
