Pet Peeves. Trust me, this list should grow over time:
ME: "Ok sir, you're having a problem with your internet. I'll hang up and walk directly over to your desk."
CUSTOMER: "Yes, that will be great"
I walk to the desk...the dude is gone. Co worker in neighboring cube says "He went to get coffee and will be back in 10 minutes"
GRRRRRRR......
Send me some of your pet peeves. If I agree, I'll post them.
