Oh yeah. Definitely. I remember freshman year in the dorm (go Terry Courts!) calling Papa Johns when they had just opened and making up random coupons that we said we had and they always granted them and never asked for them at delivery. I'm pretty sure we got two large pizzas for $5 all year long and never once had a coupon or even knew if that was a legit promotion.
I was just telling my HS senior son with sub-8% body fat about the role of $5 pizzas in my own personal freshman 15 experience. Alas, he will likely learn the hard way as I did.
