I didn't read the article, so I deserve downvotes. Uber might go after ZeroCater eventually, but this announcement is about making it so businesses can conveniently pay for meals that their staff order using the UberEats service. The screenshot is of someone just ordering one meal, for about 10 bucks plus tax (which is 22% for some reason - does it include SF Mandates? [1]) and a five dollar delivery charge. It doesn't really change it much.
