It's like that everywhere though. They put out the ads and don't get the product until the end of the week, seems like it's common practice. You can't really blame the help though. I use to work at an office supply store. I knew a lot of stuff but the people still come in thinking I went to college for this crap. I would get legal questions, tax questions, etc. If I could answer those, why would I be standing here?
When it comes to electronics, you have to keep in mind there are three types of customers. The completely ignorant: still don't know how to turn on a computer. The normal: ask everday questions. Then the geeks: who already know more than you but ask in depth questions like we study every item in detail until the wee hours of the morning.
So with that in mind, take it easy on the help, they're just trying to make a buck while they look for a better job.
