I like to share incidents immediately because they present a wonderful learning opportunity. I just observed a woman enter a mattress store. She was needing two twin mattresses for her sons (3 & 12). After some initial qualifying questions the salesperson determined that this was largely a price driven decision. He took the woman to the less expensive options and began to discuss the merits of each. In the case of this chain, the least expensive mattress that you would want any human being to sleep on is around $150 for the mattress only – by no means is this an outrageous price for a usable twin mattress.
