There are "givers" and "takers" in the world.

People with emotional support animals want to see how much they can bend the rules in their favor, to be "special." Woe upon the person who challenges them. When these people mingle with us in daily life, they take, take, take.

An emotional support animal may only not be discriminated against in housing. Supermarkets only have to allow service animals, like seeing eye dogs or those epilepsy dogs... "prescription" dogs.
