Yesterday we had lunch at a place with a somewhat interesting marketing gimmick: before you paid for your lunch, you got to roll three ordinary six-sided dice. If they all came up the same, you got the lunch for free.
Statistically, that means that if you ate there every day you'd get one out of 36 lunches for free, on average. For the guy running the place, it comes out as equivalent to a price drop of 2.78%. I think he easily gets enough increase in business by word of mouth to make it a good investment. We ended up there because one guy said "Hey, I heard about a place where you get to roll dice for your food!" and, really, how could we resist checking that out?
