There is only one boss, and whether a person shines shoes for a living or heads up the biggest corporation in the world, the boss remains the same. It's the Customer. The customer is the person who pays everyone's salary and decides whether a business is going to succeed or fail. And "the boss" doesn't care if a business has been around for 100 years.
The minute you start treating "the boss" badly, "the boss" will put you out of business. "The boss", The customer, has bought and will buy everything you have or will have - all of your clothes, your home, your car, your children's education and your vacations. "The boss" pays all of your bills, and pays in exact proportion to the way you treat him/her.
The person who works inside a big office building or plant might think he/she works for the company that writes the paychecks, but that's not true. They are working for "the boss" who buys the product at the end of the line. In fact, The Customer will fire everybody in the company from the president down. And can do it simply by spending money somewhere else.
Some of the largest companies that had flourishing businesses a few years ago are no longer in existence. They couldn't or didn't satisfy the customer. They forgot who "the boss" really is.
