The waitress, the janitor, the nurse, the hotel front desk worker, the baggage handler, and the highway crewman are all entrepreneurs. They do have something to sell and they are selling it. That is they sell their time and effort to a perform a task that needs doing. They may be drawing a paycheck from a business, but what is the business to them? It is the next customer that appreciates a waitress that is busting her tale and keeping the glasses full. It is the next traveler checking in half asleep with kids in the car asleep that is asking for a clean room. It's the next stretch of highway, that if done right, saves the government some money and lasts a little bit longer. It's that next set of bags that has some glass in it that the handler doesn't toss or smash under three hundred other bags.
DUmmies (and too many reasonable people) are all hung up on whether or not a paycheck comes directly from the customer. It doesn't matter. Each one of them can ask themselves how would I do want to be served, or how would I like to travel this road. It is not the employer that is important, it is the task.
