School fees are free to staff who live in the town. To eat at the staff resteraunt is 4QR per meal. For this money you get a salad course, soup course, main course, dessert, tea or coffee and soft drinks with your meal. It is a buffet so you can eat as much as you like. Most of the teachers I know have their evening meal there most days.
Also, because we are an hour away from Doha, I spend less on food and use lots of local produce to save having to go more than once a week.
