I once saw a guy buying Q.R. 18000, worth of cloth from a shop and then throwing Q.R. 500 as tip to the salesman. The shopkeeper felt that the guy is just window shopping as he looked dusty and sweaty. And the guy thought that the shopkeeper had insulted him by thinking of him as a poor labourer. So in order to preserve his prestige and status and to show them how rich was he, he bought Q.R. 18000 worth of cloth plus he threw a bill of Q.R. 500 at salesman's face.

It was quite a scene.
