A glass envelope for ocean bound messages

When the clock strikes five, and spirits rise, A time for deals, a pleasant surprise. What joyful period helps you unwind and socialize?

I'm a smooth operator, see? Got sticky fingers, if ya know what I mean. What's my racket, my friend, on this particular scene?

A trail between two points High above valleys and water And could be left in suspension So, to pass the time, how about a game of cards?

I have legs but cannot walk, I have a seat but cannot talk. I'm often found where spirits flock.
