Who can make the tough calls?

Can I treat Foot Locker employees like real referees? Like say I'm in the mall arguing about how it's stupid to spend $250 on a meal or $800 on a purse. Is it okay to just duck into a Foot Locker and have any employee in the stripes make the call? What if I let them blow the whistle too? Oh and Andrea you still get 2 min. in the penalty box
