What's the opposite of a Karma Slap? Good things happen to people who tip well. I took a cab today to pick up my car and left the cabby a $4 tip for a $19 ride, for no particular reason. I'd consider that a decent tip. As I was waiting for my car, the cabbie came back and dropped off a small brown bag I'd forgotten in the backseat. The weird thing is I thought I had checked that I had everything because I was also carrying my camera case and a chequebook. The package (which didn't look like much more than a work snack, honestly) actually contained some naturopathy pills, which I had just paid $50 for. So there you go.
