I would start a company, buy out all of the competition and become the greatest company there is. In this case a phone company sounds good.
I would then take this same phone company, and make it mandatory that if you are not nice to the customer service representatives you will get charged. You will get charged for every curse word, any time you yell, an any time you hang up without saying goodbye.
You'll be charged the rudeness fee.
You won't be able to go anywhere else because I'll be the best company in town.
