A boss was educating an employee on effective sales technique.
“The main thing to remember is that repetition, repetition, repetition is the keynote!” he advised. “If you have a product to sell, keep harping on it in every possible way, cram it down people’s throats and beat them over the head with it! Above all, don’t ever forget to repeat and repeat and repeat! It’s the only way to get results!”
“Yes, sir!” the employee answered.
“And now, what was it you came in to see me about?” the boss asked.
The employee replied, “A Raise! A Raise! A Raise! A Raise! A Raise! A Raise! A Raise!”
