Then when you leave the attendant will say something along the line of "hey your pokémon liked that, maybe do it some more." and from then on you can just go in your Pokémon menu and press walk with me on all your fellas in your party. It's really that easy. No maxing out friendship or anything. Just go to amity square and then leave again. Easy.
