Snowflake. If people who sit on their butts all day in front of the computer were paid to enjoy their form on entertainment, more people could afford umbrellas.(Just having fun!)
Did you read my restaurant analogy? It's around here somewhere. Those incentives are a proven business model. You're trying to tell me that coupon for a free turkey after purchasing $100 worth of groceries doesn't lure people to the store to spend $100 they may have spent elsewhere or not at all. Incentives work. Yes, people will still buy food, even on rainy days without an umbrella and if that's the case, they may choose the store with the closest parking spot as their incentive to shop there.
