Tipping nazi

I once had a roommate who was a tipping Nazi. That is, whenever a group of us would go out to dinner, he's insist on computing a 15% tip for everyone does to the last center. He also insisted that we should never use pennies in our tips.

I remember two people objecting to his heavy-handed insistence. One person pointed out that it's a waste of time to compute everything down to the exact cent, and that people should feel free to tip more or less depending on their preference. On another occasion, one person pointed out that pennies are legal tender, and that there's nothing wrong with leaving them as part of one's tip.

And heck, consider this. These people work in a restaurant. If they don't like the loose change, they can always get it changed at the cashier's till. Indeed, that's what a lot of servers do.

Mark was a really interesting character, I tell you.
