Wow. How did we get from reading about an experience one person had, from their point of view, to a kindergarden spelling bee? It doesn't matter what you think happened, and it doesn't even matter what DID happen. What matters is what the customer preceived happened. There was a communication break down somewhere, and the customer suffered for it. Period. Should he suffer for it? Probably; he didn't read the labels. TWICE. Should we jump all over him, or other responses, for spelling? Hell no. Shooting is the sport here, not academia.
I don't even think we should jump all over him for his view of the experience. Unless you are "Sue" the "manager", you have exactly dick to say about what happened.
Reading this has made me a little leary of ever posting any experiences I have, because people who have nothing to do with any part of it, and just have nothing better to do, will chastise me for having an opinion.
