I have to answer a lot of phone calls at my job, and you'd be surprised how many people seem to think that it's the olden times and when someone picks up and it's a party line and it's appropriate to say, "HELLO!? HELLO?! YES. YES WHO IS THIS?!" You called me, moron. Plus I always say who it is when I pick up. So conversations go like this:
Me: Hello, company, this is MorningGloria
Person: YES?! HELLO!? WHO IS THIS?! HELLO?!
Another thing I hate is when I pick up the phone and say hello and people respond with "Yes, HI." or "Yeah, hello." Fucking fuckers.
