Go ahead, say hello

There is an office building which I walk past most days on my way home from work.

Through the window, I can see a huge poster on the wall that says,

"go ahead, say hello"

I assume that the poor people in that office are telemarketers or some other lucky people who get to talk to people on the phone all day, and who are just waiting to be given permission to say "hello."

Then again, I have a friend who does work in a call centre and who is not allowed to say "bye" - it has to be "goodbye."

If I worked there, I think I would mention that poster in my resignation letter. Or, if it didn't cover a whole wall, perhaps use it as stationery for my resignation letter.
