The petrol station on the North Road near Summerland would always short change me by at least 1/2 riyal,if the petrol was QR31.50 they would ask for QR32 saying the tank was full.I suspect most people wouldn't be bothered by 1/2 riyal.It's the principle of being cheated that's annoying, not the money.

May your dreams take you travelling all through your life.
