Taco Bell

At 8:00pm on a friday night there is no reason for there to be no visible employees and the open light off. I don't understand how a fast food place can make it so ambiguous as to whether or not they are open. Some employees are incompetent, my order has been wrong at least 20% of the time I go there; items have been missing, and I have to say what I want a minimum of three times before they understand.
