A few days back I was waiting for the bus at the bus stop.  Before getting into the bus I had prepared the exact amount of coins to pay for the bus fair and when I got into the bus I put these coins into the box meant to collect the bus fair.  I thought that I had paid and wanted to get inside.  However the bus driver called me and asked me in an impolite way if the coins were stuck at the opening  of the box.  He had not seen me paying and there wasn't a stack of coins in the box.  I could not understand this and the driver kept questioning me.  He made me feel angry and at last i inserted a dollar coin in the box just to get away from him.  Later I found that I had forgotten a few coins in my pocket and had not paid enough for the fair the first time.  After I had entered the bus I could still hear him scolding me and I felt disgusted.
