All this is true... in hindsight/Monday morning quarterbacking etc (as is in most cases), yes, a phone call or online verification or shipping would've been easier, but most posters of those comments I think are missing the point.
I think the point that the OP is trying to make is that the CW customer service at that location by that employee let him down in this situation. The resolution was not the point of his post, though it is a result (resolution or non-resolution) of his point. Yes, he could've been proactive and called ahead of time... and he knows that now (as we all do), but the employee could've have also been more helpful to help him get the item he wanted, a sale, a returning customer, and avoided bad publicity such as this post and word of mouth.
Customer service is something that is really lacking in our current business society, mostly by the big chains.
I would much rather support and be able to go to the local store to buy my items, even if it's at a slightly higher price than online "IF" I get great or even good customer service and assistance, but that is rarely the case anymore. And big businesses wonder why and gripe that people are buying more and more items online. Go figure.
BTW, I have also visited the Valencia CW, and his experience there does not surprise me... Thus, I have stopped going there unless absolutely necessary, which thankfully I haven't had to.
