Watched my two orders sit on the counter by kitchen, waited for all customers to be helped and approached cash register. The girl said she would help me in a minute. I just stated my food has been sitting there for awhile. She said again in a minute she would help me.
Then she went through the tickets that were hanging and made changes or something, not sure. Not exactly sure what she did but seriously act lost. I returned to my seat. Yes, my orders still sitting there.
Than after a few minutes, my order was given to me at the table. Food was almost warm. Told her we would never eat here again. Then I noticed the burnt crisp 1/4 top of bagel, that section was not fit to eat .
I received a blank stare when I said we would never eat here again.
I have ate here over the years and have never had this type of service. Not sure if is related to just one employee.
I know new customer orders are important. But sh are those waiting for hot food.
