Why does Panera suggest you tip now? What extra service are they providing, exactly? The food is good, but it's expensive, definitely not fast and half the time they mess up my order (last time I came, they put the wrong salad dressing on, and when I pointed it out, they apologized but did not offer a voucher or anything). Then they ask if I want to tip them?! So annoying. No, I dont, but I'm sure others are tipping out of a sense of misplaced obligation to do so. I hope they remove this option from the checkout process soon.
