I saw this happen in the hall near my brother's wedding reception. A female manager was upset with a caterer, who had signed up for a one-person shift. She said she didn't think he could manage the service alone. She was sternly all, "I've told you not to sign up for shifts by yourself, I've been very clear about that, I don't know how much clearer I can get for you to listen. You need someone there to give you instructions and guide you." And then the caterer said, "You know, I'm beginning to see why you work so many wedding receptions." What does his comeback mean? Whats the implied reason?
