I remember after the PW football game during my boys' firstie year, the folks from Chick-fil-A were in the parking lot (season ticket holders, they) passing out all kinds of "free stuff" coupons. Free whole meals, not just a sandwich or a drink or fries. "Free family dinner" for four - that was a good coupon as it included drinks and brownies (I think).
Other restaurants, both fast, and slow, have specials during PW and football weekends, and graduation. They are a great bunch of people there in COS.
