Some of the stupidest things customers have said to me

Why people act more idiotic towards people in customer service I will never know
  1. "Do you do food here?"
    No. This is a restaurant. With menus on every table. Of course we don't serve food here.
  2. "Do you have Guinness?"
    Nah this is an Irish pub. In Ireland. What's Guinness???
  3. "What is coleslaw?"
    How can I even describe that.....
  4. "Can I have an Americano?" Me: "yeah, so a coffee?" "No an Americano"
    When pretentious customers make a tit of themselves >
  5. "How will this top look on my daughter? She's about your age"
    That literally tells me nothing. I don't know who your daughter is. Let her buy her own clothes.
