Yesterday was my first day to work on Senior Citizens Discount day, the day when if you're sixty or older, you ger a 10% discount off your purchases.
The first lady through my line had pure white hair.
So I asked if she "qualified" for the discount...she was 56*. I decided I wasn't going to ask anyone anymore.
About the 10th person through my line told me that she qualified. After I had already completely finished her order and I handed her the credit card receipt to sign.
At that point, I decided that anyone who looked even a day over 20 was getting the senior discount.
