They weren’t very educated on service animals. I have Celiac and I bring my service animal specifically to aid in grocery selection to make sure I can safely consume the food I purchase. I was approached by many employees asking if my animal was a service animal, that in itself is fine (maybe annoying, but well within their right), my issue was the employees telling me food allergy service animals weren’t ADA compliant. Maybe if you require your service animal for food allergy issues shop at another grocery that is less aggressively ADA ignorant.
