The employees and subcontractors who work at Merck in West Point (Lansdale), PA and Whitehouse Station, NJ. These people drive like assholes while talking on their cellphones and totally disreagarding traffic laws and common coutesy. They speed through residential neighborhoods going to and from work. When they frequent local businesses they are loud and obnoxious pissing and moaning about their co workers, bosses, and subordinates.
Those Merckoffs stayed for hours, got separate checks, and then stiffed the waitress.

That Merckoff in the silver BMW came flying around the corner and then rode my ass all the way to the traffic light.
