If the food allowances are the same for all employees, then there should be no preference shown to some employees over others in serving them their meals. There must be equality in the quantity and quality of the food served as well as in the manner of service.
Otherwise, that will be a form of oppression and a wrongful consumption of other people’s wealth, since the same amount is deducted from each employee's salary.
Allah commands us to be just and warns us against injustice. He says: “Allah commands justice, the doing of good.” [Sûrah al-Nahl: 90]
And Allah knows best.
