1. You really should tip for take-out. I mean, sure, they don't have to clean up after you, but they went to the trouble of putting your food safely into a container and then maybe a plastic bag, didn't they? Never mind not losing your order in the first place.
2. Tips on beverages should be a dollar per. This is an extremely good deal for baristas, and a slightly less awesome one for bartenders. Which isn't really fair, come to think of it, because belligerent drunks are probably far more annoying than the insufficiently caffeinated. But drunks are also far more likely to be jolly, generous, and bad at math.
3. People who speak disparagingly of others in public should be subject to a mandatory time out, accompanied by a 'this is your life'-style montage hosted by Jon Stewart.
4. Only those who receive paid sick leave from their jobs should ever be subject to cold and flu viruses.
