Is the following review positive or negative?

If no stars was an option, it would happen. I ordered my food, pulled up to the window and before I handed over my payment I saw a roach on the wall. Took a picture(which I will post) and told the cashier. She looked, shrugged her shoulders and said"not the first person to say something". I get it, you work minimum wage and flip burgers for a living. But in any restaurant, cleanliness should be priority.
negative
