A CHEF
You can buy a white chef hat ( and white chef apron ) at JoAnn's for about $7-8.00 each.... If your uniform is a white jacket it would be perfect. Bring a wooden spoon to keep the olle' guys n gals in line..lol....other Scary extras would be red like stains for blood on apron...a ( toy ) meat cleaver.... blacken teeth ...lol
