Yes. Quite often, sadly. Usually when I'm driving, but also when I see someone blatantly littering in front of a perfectly good trash can or absent-mindedly blocking an aisle at the grocery store.
Integrity is no longer valued in our society because it's an intangible virtue that you can't directly benefit from, so many people toss out that decorum for marginal gains. The reason I throw my trash away in a trash can is because I respect the social contract and I don't want to leave a mess for someone else to have to clean (even if it might be their job to clean it) not because I'm afraid of being judged or confronted by others, which I think is the only thing keeping most people on the right side of the equation these days.
The Shopping Cart Theory is a fantastic way to determine if you are dealing with somebody who doesn't respect the social contract, and indeed, that attitude transcends mere niceties and seeps into their personality - laziness, selfishness, and a general lack of respect for other people's time and property.
