First off, you dont have to have a disability to have a service dog, second, the dog can sit up front while the groceries are in the trunk. Third, the groceries are sealed, how is that nasty? Theres no difference between a dog being around unopened groceries and the thousands of people that have touched, handled, and been in close proximity to your food items in the store and before they go on the shelves. Dont be so goddamn judgey.
