Jiffy Lube review: disrespectful employee

I came in at 6:50pm on Friday, April 20, 2012 to get an oil change. The first employee that greeted me was very nice and friendly. My car was pulled in the bay area. My car sat until 7:00pm (which was also closing time). The manager ask some one to service my vehicle. Another employee by the name of William came into the waiting area were I was sitting and starting cursing and throwing things around in the lobby area. He slammed the restrooms door and was looking at me with a very disturbing look. I am very displeased with the behavior of this individual that is suppose to be providing customer service in a professional manner.
