Write a letter explaining you were disappointed and suggesting what could be done to improve the situation
Dear Sir,
I am writing to express my dissatisfaction about law quality of meals which we ate in your restaurant yesterday evening with my whole family.
Firstly, I had enquired 3 portion of stake and 1 portion of porridge for our daughter which would be made with rice and we were given 2 portion stake which was thrown out from another customer so I had to swear your waiter but she aggressively answered me, we had just move out there without paying any bill.
Furthermore, unexpectedly we were eyewitness waiter which works in your restaurant was servicing when she had drunk whose name was Julia.
I believe that your waiter could not suit to work in your restaurant and I believe you could be dismissed this waiter who do not care about herself due to her own badly service for your regular customer.
You had better give this matter your urgent attention, or I absolutely will have to change my daily restaurant.
