I really dislike carrying cash. It's dirty, makes my wallet annoyingly bulky, and always seems to disappear faster than it should. What's even worse is ending up with a pocket full of change after being forced to buy something with it. The horror! I used to catch my Mom throwing away pennies when I was kid because she didn't want to carry them, but frankly, I can't bring myself to do that. I'm too cheap. So I do the next best thing...dump the change into my wife's bottomless purse to never be seen again. I guess it has basically the same effect, but mentally I can handle it much better.
