There is no reason NOT to have your "helper" with you, and that is what most store clerics call them, if you need. Get him trained and certified. While the small disks or ID tags are good, and people really aren't supposed to hassle you, the service vest is BEST. Most easily recognized, is the royal blue one. Most visible, but not cheap, from what my BFF said w/patches, shipping etc, approx $35. And REALLY...TARGET, get a life, after you spent money. AHH, things like this really pi$$ me off, so many people have disabilities that are not "visible", it doesn't make them not real or developing. Sorry MY soap box issue.
. Because of my BFF. One other point, and not to be aggressive with the store people because most are just caught in the "middle" between policy and law, BUT KNOW YOUR RIGHTS, the ADA web site has some good info, the humane society, even your local free law web site if you need. A good tactic is, the store people or who ever, look them right in the eye, SMILE BIG, and thank them for their concern. STATE VERY LOUDLY "I DON'T OWN A PET, HE IS A SERVICE ANIMAL", smile and walk away. No discussion, nothing, not your problem. If and a big IF, they push, ask for THEIR piece of picture ID, write down the info, legal issue. Then as in all things vote with your $$ or rather where you spend your $$ and make sure corporate understands WHY. This part is the legal issue, a corporate thingy, very sensitive, everyone wants to be politically correct. Sorry this post was so long, it really is a soap box issue with me, too many of our brothers and sisters who have a real need are denied help and care when just the smallest and most loving little people (ours) could be of so much help. Good luck in your search for the help you are looking for.
