I work for a dining group and our restaurants regularly show up on GrubHub's app and website as delivery options through their service. They post outdated, incorrect menus, then allow customers to order from them, pay, and be left either with food that doesn't match their incorrect menus or no food at all. Our restaurants receive no payment from GrubHub whatsoever, so this is stealing from businesses, and this has happened multiple times. Please don't support GrubHub, either as a business or as a consumer.
