It varies person to person & their life styles.

Some people use Karwa buses to reach Al-Khor form Doha and they have to pay less than QR.5/- that's only a single buck!
Can you imagine this somewhere else in the world?

A bar-B-Q for 2 with fresh juices in a restaurant or a buffet lunch/dinner costs around QR.100/- that's around 25 dollars only :)
that's quite reasonable.
