(Our pool doesn’t allow children who are non-swimmers to be in the pool without their parent. A mom comes in and throws her child in the pool with water wings and goes to leave the pool.)
Me: “Ma’am, you cannot let your child in the pool without you in there with him.”
Customer: “Well, why?”
Me: “It is unsafe for a non-swimmer to be in this deep of water alone.
Customer: “He can swim just fine! I put his wings on.”
Me: “It is possible for him to drown even with wings on.”
Customer: “If he does, just call me and I will come swim with him!”
