Unsanitary and unhygenic preparation.
Watched as a staff member got up wiped his bare hands on his shirt and started preparing my chicken burger. he did not wash, put on gloves, use paper towels to wipe, and even adjusted his pants around his waist.
For the record, I did NOT eat that burger, I tossed it out, I lost my appetite.
Serves me right for wanting fast food...but I did have coupons.
