Yeah, the fifth (or whatever number you use if you're of a fake denomination) commandment says thall shalt not kill but it defines killing as general acts of rudeness as killing. "Oh no, you didn't say excuse me when you reached for the salt. You've killed my spirit!" I'm in the camp that believes that Jesus makes a distinction between the two types of "killing" but I'm also in the camp that wouldn't leave these on Subway tables.
