Sammy is a cashier at a supermarket. A group of girls walk in,& it seems like he cant get his eyes off of them.
So while the girls are shopping Sammy is "minding his own business" until he wants to get the girls attention that he is not getting at the moment.
Sammy makes a overrated scene in front of everyone at the supermarket. And he quits his job. He was expecting the girls to notice him& maybe have a conversation with him about him quitting his job or something.
But instead, the girls minded their own business, checked out,& proceeded to their day.
"Thank u, have a nice day."
So, Sammy leaves the supermarket& is just now realizing what he has done. He just quit his job to try& talk to some girls who are not even worried about him.
