If they could not pass simple mathematics, why this people was hired I paid RM10 and ask for RM3 fuel, yet the cashier return the change of RM3. I said "pamp 4, 3 ringgit". Mental retard? When I argued to get the exact change another Indian lady who was busying with tapping her iphone 6, claimed that I only gave rm3. Lol i give red bank note how come only rm3, colour blind or play too much iphone already?
