if you have lots of complaints on a particular restaurant then eat somewhere else! qatar has thousands of restaurants to offer and noone pushes u to eat in fridays'!

u already noticed before that the food was getting smaller and smaller every time u visit there but then u still go in the same restau and only stress urself in giving negative comments on their food/service...

and if that was the case,  i believe that u shouldn't blame the manager nor the saleslady coz they can do nothing more aside from being sorry and change your food or even give u discounts, or make it for free.

what else do u expect them to do? close the restaurant coz u found a pc. of food in your glass of  drinks?
