most of the time it is just a greeting like saying hello.
Sure they do, when you have the money you owe them in your hand!
I guess it is an ex<x>pression or a habit. It is just a liner.
When I say "It's good to see you," I really mean it.
is the emphasis on SEE or on YOU? I am sure most people are glad they enjoy the gift of vision... :D
Some do. I'm thinking that many people just say it like they'd say, "How are you?" Mostly as an all purpose greeting.
I'm not sure. Some folks are always over the top friendly, but then, there are actually people who are glad to see other people much of the time. Kinda depends on who it is.
