This man is either an idiot or just incredibly impatient. He doesn't sound like someone with particularly stellar "people skills", flipping the forget out after only two or three correspondences. He also sounds unbelievably entitled. Anyone who's dealt with Dell Customer Support and repair knows that this mishandling/mislabeling by warehouse staff is minuscule compared to the stuff Dell pulls on a daily basis.
I can't really talk about the staff though, because I've never had any Newegg products shipped from California, but instead from their New Jersey facility, which takes about a day of UPS Ground to reach my house in MA (about three days in upstate NY currently). I have never had a problem with Newegg, the few times I've dealt with their customer support has been for minor things and the issues have always been dealt with quickly. If anyone's stupid enough to jump to this guy's defense, I don't think they're the sort of people that Newegg needs the patronage of, anyway.
