You CAN be in front of the store, as long as you are standing on the sidewalk, because they can't OWN the sidewalk, that's public property. An outside mall is the same thing, you can be on the sidewalk in front. You shouldn't be in the street, because the police WILL tell you to move out of the street.
Kindness and respect should be shown to all animals, no matter if they are furry, scaly, big, or small. Be a hero to the animals and GO VEGAN!
