"sandman on the rocks"

go into a bar and ask for a sandman on the rocks and he'll grab a glass with ice and go out to the front door of the bar where the flowerpot-filled-with-sand ashtray sits by the door. he fills it with sand and an old cigarette butt. he brings it back and hands it to you at the bar. you look at it and you say him, "just put it on my tab".
