One of the guys on the airsoft forum I use had this:
Not really a joke, but this was the funniest complaint I've ever had the pleasure of dealing with at work so I thought I'd share it -
Me - "Good afternoon, how can I help?"
Customer - "Yeah, hi, there seems to be a problem with your phone system whenever I've called in today."
Me - "Yes sir, and what seems to be the problem?"
Customer - "There's a bunch of c*nts on the end of it."
Cue me pissing myself, and congratulating the guy on destroying my entire team in one sentence
Myself... Well I wanted to answer the phone "hello, dominos pizza" for the day, not advisable when the first person you answer the phone to is your boss....
