Only if they're really tired or sick. Or if I might say something that would really irk them if they were already in a cr@ppy mood. We try to help them feel better by expressing empathy for their situation, but sometimes people aren't usually happy because they just wish to pay for their items, go home and try to feel better. We've had folks arrive from a hospital visit, only to learn that their insurance claim didn't go through. That makes more work and pisses folks off. Or if the reason they visited our store, we didn't have what they were trying to find, out-of-stock, discontinued, whatever. Or if their day was exceptionally confusing or frustrating. These are the things that generally lead to debate or issues. That being said, only on rare occasions do I encounter someone who tries my patience or someone who is difficult to conduct transactions with. Customers are usually forgiving if we're short-staffed one evening, if there might be longer lines during peak hours, or if a customer is somewhat slower to conduct a transaction if they're performing a refund or writing a check. Management is there to help front store employees, but not all employees are quick to page a manager to help out if the lines begin to pile up. Fortunately, this is not the case with me. When customers have large quantity purchases or one can see they've got a full cart, it just clicks that one needs to demonstrate practical knowledge and ask for management to step in to assist. Most of the kids do it their way, but could use a little help to know when to ask for help. EDIT: Working for the store for 15 years has afforded me more experience than kids who've worked there for only a season or 2.
