zero, i had a caller this morning who wasn't the nicest person ever. she wasn't straight up mean/rude, but... still. lol
I once had to deal with a person which changed his name by deed pol to Mr Elvis Presley.
Everytime I spoke to him on the phone, I had to put him on hold while I stopped laughing!
You know how when someone is on the phone, you say things like ok, um, yes, um etc just so they
know you are still there listening.
Well I decided that one day I would try to get in a "ah ha hu" and see if he noticed.
Well every time I spoke to him my sides were almost splitting with trying not to laugh, then
one day I did it. "Yes, ok, ah ha hu!"
I had stomach ache with the effort of trying not to laugh and he never even noticed!
