+1 on the above. In the shop that I was working in I saw a number of people be told that they "would get used to the position" when they became more fit. While a portion of this is true, I often wondered if the bikes would continue to get ridden if the customers found them uncomfortable after a short while. My guess was no.
I do have to say here that I also think the customers often had unrealisitc ideas as to what was important regarding riding a bike comfortably. I had one guy who's primary question was "What does it weigh?"

He ended up buying a very light, very aggressive, very expensive, full carbon bike and fitting it with a hybrid stem because the saddle to bar drop was to aggressive for his fitness level. I had tried to steer him towards an entry level tricross or a flat bar style road bike before he got annoyed with me and sought out another sales person. He did not seem to think the extra 30-40lbs he was carrying on his body was something to consider as well. Anyway his money, his choice. I hope he enjoys it.
