history: These people at work are so disrespectful and racist!! these people at work are so disrespectful and racist!! I can't wait till i quit! I'm an armed guard and they want me to help customers to find products and i'm not there for that!!
current: Hmmm sounds like an unpleasant job. Maybe they ask you for help because you're the only one around? It doesn't hurt to help those in need.
next: i understand, but i'm there to make sure everybody is safe. if i start helping customers i might miss a person getting a gun out or something like that
