Like what I think cosmokramer implied, in sales, one just can't please all the people all the time! Hence ones right to refuse service to anyone, hence ones right to refuse to buy from a seller.

We RARELY hear about the hundreds or thousands of positive transactions, what we hear about is the ONE isolated negative transaction. This has been hugely amplified today thanks to the internet and instant communications.

I love this forum as at least we often hear both sides and can make up our own minds and not be sheeple.
