We love pop-up shops in our house.  Often there will be a book store, complete with scanners in the middle of the lounge.  Often, they will sell ice-creams and other treats from the car window.  While they are only pretend, I'm not sure whether to embark on the "stranger danger" or "drugs are bad, ok?" speech.  The Christmas shop above is the result of leaving a box of unhung decorations in the lounge.  How could you resist such exuberant shop assistants?
