Poor service and ignorance

On my arrival at the restaurant I found a cashier whom was staring at me until I was the one who greet Frist. I bought my meal then " family and friends" type of meal and the dessert. The cashier gave me the table number with cool drink. While seated the waitress came carrying the meal I ordered which one set of the meal was not outstanding. I thought they will still bring the remaining part of the meal, I ate and finished while still waiting for the meal. I ordered dessert hopping they will bring it after meals I stayed with it until it gets cold. Nobody checked on us until the time arrived to leave the restaurant. Poor service I experienced and negligence of customers.
