Cash discount

After I collected my change from my pre-paid gas, I found that the cashier short-changed me a few cents. I told him, and he gave me the rest that was due. Sure that he did this on purpose, I counted my change carefully the second time I was there. Same thing happened. When he was collecting my change the third time I was there, I said, “Don’t short-change me on purpose again.” A big smile swept across his face. Busted! The cashier was not embarrassed at all. He loved that I caught him. The business must be making a nice profit short-changing people, who don’t count their money.
