A former Wendy’s employee was treated like a piece of meat by her supervisors at the Rockefeller Center fast-food restaurant, a lawsuit charges.

Alexis Weller, 19, told The Post a manager named Keith traced his hand across her buns as she closed out her register for the day.

“I instantly became aggravated,” said Weller, whose attorney, Matthew Blit, filed the suit yesterday in Brooklyn Supreme Court.
