Constantly messes up my order every time I come in. If I ask for no egg on my sandwich why is it every time I get to my destination after ordering there is a damn egg in my sandwich. I ask for extra bacon and there is never extra bacon put on my sandwich. The lady that order takes on front counter always has a nasty attitude sighs whenever my order is given and is just wicked rude. Totally unacceptable.
