[Robot-Lobster]

How about a girl (maybe named Samantha) who is so outrageously curvy that her boobs and butt rest on the floor? She rarely waits on customers because it's so difficult for her to maneuver around the tables without knocking them over, but she helps out by providing all the milk for the restaurant, and also by serving as a couch in the breakroom and as a table for large parties.
