It seems like today people want so much information from you. You have to spend 1-2 minutes on the phone, after you get to talk to a human, before you can ever get down to business. They need name, account number, (again) last for of something or other and on and on.
There is a fine balance between good customer service and down right annoyance. Anyways, I love the look on these peoples faces when I give them my email address of some firstname.lastname@example.org. I can not tell you how many tech support people have bust out in laughter when I give them this email. Kind of lightens the whole mood and even has a calming effect when talking to some of the less, shall we say, less than helpful customer service reps.
