A friend of mine was telling me a story about his son. Apparently his son who is nineteen and his buddy went to a local Taco Cabana. While they were in there they noticed some buy one get one free coupons and snatched up a few. They then ordered a heaping mound of food and when presented with the bill they gave the cashier the coupon.
"I'm sorry, but you can't use this." the cashier informed them.
My friends son got really upset, "Why not," he asked?
"Well sir you aren't a Senior," was the reply.
"Sure I am," he said presenting his school ID proving he was indeed a Senior.
"No Sir," the cashier explained. "These are for 'Senior Citizens', not 'Seniors in school.'"
