I work in the electronics department of a big box retail store located in a...shady part of town and get a lot of...interesting customers.
We are usually alone in the electronics department, but during times which are known to be busier there will be two of us. At one of these times, the phone rings.
Me: Hello, this is (store) electronics, how may I help you?
Phone: Hello this is hewwo thissshhh hwwwooo sshhhh WOOOMP WOOOMP WOOOMP WOOMP WOOOMP
The person who called me had me on speakerphone, possibly hooked up to a speaker, and I was getting feedback.
Me: I'm sorry, it sounds like there's some feedback. Could you possibly turn the volume down or take me off of speakerphone?
Phone: (after a little bit more feedback) [inaudbile] Can you hear me now?
Me: Yes, just barely though. It sounds like your phone is having some problems, though. I can only barely understand you.
Phone: I'm [something something] for a car [something something].
Me: I'm sorry, I can't understand you. You're looking for a car something?
Phone: No, a [something something]
Phone: Look, [something something] is golden [something something].
Me: Ma'am, I'm really sorry, but I just simply cannot understand...
Phone: Are you f!ing deaf.
Me: No, it's just...
Phone: ARE YOU F!ING DEAF?
I hung up the phone. I refuse to be treated like that. If (when, really) someone curses at me, I immediately refuse to help them any more unless they apologize (they never do). I look at my co-worker and let her know what just happened in case they call back. And they did, almost immediately.
Me: Hello, (store) electronics, ho...
Phone: DID YOU JUST F!ING HANG UP ON ME?
My co-worker stifles a giggle. She's in the middle of checking someone out at our register when the phone rings again, so she offers to trade with me. I finish ringing the person up, listening to my co-worker talk in the background.
Co-worker: Hello, this is...yes, he's not here now...I'm sorry, what?...I can't understand you, it sounds like there's a lot of feedback on...no...I...what? No. Goodbye. click
They cursed at her and called her deaf, too. Apparently it's beyond belief that the problem would be with the customer's phone and not our ears. A few seconds later the phone rings again.
Co-worker: Hello, this...nope! click
A few second later, it rang again. We ignored it. After the customers at the register were taken care of, we called our manager over to explain what just happened in case we got a complaint. I'm pretty sure we didn't, but our manager did tell us that we would be fine if we did.
