Tom Thumb does too. The 1 near my house has a guy that talks to himself all day. He does all kinds of work there, bagging groceries, wrangling carts, cleaning the floors, etc. Over the years, I've seen some cashiers have a look of death on their face when he was bagging groceries for them, and others that had a more positive attitude about it. I mean, he would literally talk the entire time, never shut up; even bringing the other employee's names into his conversations. He would echo the PA announcements over and over and over and over. I know that one time the managers had to have a talk with him and his parents, because he would comment on what people bought. I was there in line to hear(paraphrasing), "the lady is buying tampons, what are tampons for, I've never seen a tampon, can you eat a tampon?" It took all my strength not to bust out laughing.
