sorry no hot dog jokes at the moment. I don’t think he means the jokes to be a main attracter as much as a wisp of humour for the few moments a customers gaze runs over the cart. The owner of the sandwich shop my wife runs has the big store sign and under that a build your own on each store, each week he changes the wording, sometimes its just an ad , sometimes a humorous play on words. I don’t know that it draws in any customers but I don’t think it hurts either
