The first rule of working at jobs like Wal*Mart is to not entrust your personal life with your co-workers. OK so you like this girl. Well that is between you and her. It's not Chris's business and it sure as shit isn't Leon's nosy-ass business. Leon pretty much shot your chances to hell with her. The best advice I can give is to stop talking to this guy all together. He's obviously a loser/creep and the fact that you continue to associate with him makes you one. You are what you hang out with.
