There was a hint in the post about the real solution: he should've been pushed in via wheelchair on his first visit to avoid his having to be accommodated in a different way in the future. My daughter is "on the spectrum" and we try very hard to not create situations that require us to jump through hoops to avoid her autistic meltdowns. If she makes unreasonable requests, we have to say no and steer her away. For instance, at one point she asked us to remove the tags from her stuffed animal. Then it became a requirement to remove all tags. It's taken a while to cure her if that trigger. On the other hand, if we ever need to know the name of a particular dinosaur, she has us covered.
