On being telephone adverse

The telephone is rude. I hate making calls and I struggle during phone conversations. I hate that I can't see the reactions of the other person. At work, I will not pick up the phone if I have a customer in front of me. That customer has gone to the trouble of getting into their car and driving to the mall. They have made an effort. The caller is still sitting on her butt at home, and nine times out of ten she has a completely uninformed, stupid question. I hate that I have to be polite to such people. "Do you have any brown Rockports?" Yes, several. What model? "I don't know. It's brown and has laces." Ok, that narrows it down to about five. "Could you check and see if you have those in size 10?" All of them? "Yes." Fantasy answer: You stupid selfish lazy bitch. I have other customers who are now waiting for me, and you want me to spend 15 minutes as your personal shopper? Go fuck yourself.
