Talking to a customer, she said, "No, I didn't say the number four the first time. I said the number seven. The two numbers don't even sound alike. How could you have heard four when I said seven? I mean, I could understand if you think I said eleven, because eleven sounds a lot like seven. But I never say eleven. I heard that some kid couldn't dial the police once in an emergency because his mom had told him to dial nine-eleven instead of 9-1-1. The poor kid couldn't find eleven on the dial pad. So I never say eleven, so you couldn't have mistaken eleven for seven. Hold on a second. I'll just double-check. Oops! I think you're right. It is a seven. You know how sometimes people cross their sevens and make them look like fours? That's why I guess I said four. You're right. I apologize."
