I find it hilarious that New York Fries--a fast food restaurant that literally sells nothing but fries (and hot dogs)--has a loyalty program. (Okay, they also sell a few poutine variants, but that's just French fries with toppings.) A loyalty program. Buy 10, get one free.
On the other hand, apparently members can get free fries tomorrow in honour of National Fry Day, so now I'm kind of thinking about joining.
