Oh! A BIG work related one....People who confuse us (telephone company) with cable tv or power.

I get things like:

Idiot: "Mam, are you working on my line, my cable is out."
Me: "No, I am not. I am working on your neighbor's telephone line."
Idiot: "Mam, are you working on my line, my cable is out."
Me (louder): "No, I am not. I am working on your neighbor's telephone line."
Idiot: "Mam, are you working on my line, my cable is out."
Me (shouting): "No, I am not. I am working on your neighbor's telephone line."
Finally, I come all the way down off of the pole...
Me: "I work for the PHONE COMPANY, not cable tv. I do not touch cable tv, and I know nothing about cable tv. You will need to call the cable tv company."
Idiot: "Well, can you come check out my cable?"
Me: "I cannot, I work for the phone company, not the cable company."
Idiot: "Well can you come fix it? I think you may have accidently disconnected my cable instead of my neighbors."
Me: "Mam, I am not anywhere near the cable lines, I am working on the phones."
Idiot: "Ok, sorry. So, do I just call your company to have a repairman come out?"
*edit* I forgot a part...then they say (if they even get it) "Are you sure?" I am damned sure what I am working on. You can't confuse power, cable tv, and phone lines. It's impossible and deadly.
ARGH!

Or the classic pick up line I get literally weekly...And every guy snickers like he's original...
"Hey, baby...My power is out, wanna come fix it?"

Read the truck...I am the phone company, not the power company!
