You know, my friend's company sells shoes. Due to a problem in his factory, the soles of all his running shoes had a defect. Athletes could injure themselves by using it.
As the shoes were already out there in a complex distribution chain, a total recall was difficult. So, he put out an apology and a notice to athletes to not use shoes of that batch and wait for something better or use other good brands.
I went to a shoe store in London the other day and saw a shoe of that batch and told them not to waste time showing it to athletes as they wont buy it. Someone with less intense requirements may buy it and use it for some simple walking around etc.
You know what happened?
The store salesman refused to believe that Athletes will not use it. He wanted "evidence" and "sources" from me and demanded "proof" that athletes will not use the damaged shoe (acknowledged by the company as damaged). He was soo joined by other salesmen in the store - all clamouring for "evidence". Someone started booing me too.
I decided to go out and have a good time in London and do all the other stuff I had to do.
