I work in the Electronics area of Massive Retail Chain.
I received a call and picked up the phone. This was the exchange (C for Customer, M for Me):
C: Do you have any phones with AM/FM radio?
M: Are you asking about cell phones, ma'am? I know that some smartphones have radio receivers in them.
C: No, I mean a regular phone, with AM/FM in it.
I had never even heard of such a device before, a standard home phone with a radio built into it.
M: I don't think that's a thing anymore, ma'am. I know some cell phones can do that, but I'm not aware of any standard home phones having that in them. I'm pretty sure they don't make those anymore.
C: ...well then, what does Other Store have?
M: I don't know what Other Store has, ma'am.
At this point, there was a loud CLICK. I said "hello?" a few times to be sure, but it was quite clear she'd hung up. The cell phone vendor who works in our store was in the next aisle, and when I came over to see him he was already starting to laugh, since he'd overheard what I was saying. Neither of us could believe it. A strange product request, followed by asking about another store's products (I have a hard enough time remember what my company stocks, let alone another one!), and then a rude hang up.
