It all seems so familiar to me, I've heard at least 3/4ths of them from customers. But by far my favorite (I've had this happen at least 10 times a year).
Customer calls:
Is my computer done yet?
(ok, how am I supposed to know)
My answer:
I don't know yet, can I have your name ?
I mean, really, how am I supposed to know. If you were my only customer, how would I stay in business.
