Remember when postal workers used to have a reputation for going POSTAL?  26-year-old Rachel Meyers is a U.S. Postal Service worker and amateur bikini model in New York . . . and she's singlehandedly trying to bring that back.


Rachel went to Century 27 Beauty Salon in Manhattan last week to get her hair done . . . and she felt like her stylist BOTCHED it.  So she started yelling that they'd knotted her hair . . . and then she went OFF.


She started screaming at everyone, smashing beauty products, and throwing chairs, hair dryers, and other beauty products around.  And she was in her post office uniform the whole time.


Most people got out of her way, but a 52-year-old woman who was getting her hair done at the time took a curling iron to the leg, which left her with a cut and a bruise.


Rachel was arrested and charged with five misdemeanors, including assault, harassment, and criminal possession of a weapon.  She could be looking at up to a year in jail.
