No More Tips

Anyone else get annoyed at the presence of tip jars at every restaurant you go into these days? I don't get why I should tip at Chipolte when I don't tip at McDonald's? Aren't they both doing the same thing - making food??
And the one that bugs me the most is Papa Murphy's. I drive there to pick up my pizza and then I'm expected to tip??? Screw that!

Here's an article talking about tip jars and why the author hates them as well.
