"Bring your glasses to the bar" is a normal enough cry at closing time. And going in to clear the ash-trays and collect the empties isn't the same as spending the whole of youir working life having smoke blown in your face.

If they hadn't gone round knocking the old bars into open plan lay-outs, it'd be an easy enough change to make in most pubs.

It isn't all that long since the expectation was that smoking was something people would do in a place set aside for it, and maybe even wearing a smoking jacket and so forth. Like a lot of innovations, this is another case where in a way it's getting back to old ways that had more sense than people appreciated when they abandoned them.
