The guards are told by Safeway management to ignore the problem because many people who aren't blind have letters from their doctors about 'necessary companions'.
I am frankly offended by any dog in a grocery unless it is a guide dog. I avoid Safeway when I can and have significantly changed the categories of food I buy from any grocery. Meat and bread must be sealed among the many changes in my shopping.
I have seen dogs climb up and eat from deli racks. I'll never buy from a deli, cheese or an open bread rack in any grocery. I only have two concerns. One, I've smelled what a plate that has been licked by a dog smells like. Dogs perspire through their mouths and noses. I can smell that. Two, most dogs spend most of their waking hours licking their asses.
A retail food store policy against dogs (with few exceptions) would be easy to post and enforce.
