1.   A barman was polishing glasses with his back to Rain.

2.   She put the money in the till, walked to the other end of the bar, and began ostentatiously polishing glasses.

3.   I can see the bartender polishing glasses and hear kitchen sounds coming from behind closed doors.

4.   The bartender slowly wipes down the long, gleaming bar and polishes glasses.

5.   The glass can be polished by a good auto glass shop.
