Should Men Wear Ties At Work?

While visiting with some friends of mine who are all business professionals, I asked them if they wore ties at work.

My banker friend said that he did from Memorial Day to Labor Day.

The investment advisor wears one every day. And the outside salesman said that he wore it for appointments, but took it off when he was done talking to the client.

So, my questions is this, as a customer, would you prefer that the people that you dealt with wear a tie? I'm curious to see the responses.
