I think the best thing you can do at a restaurant as an aspie is take their feedback surveys and complain about the things that bother you.  For example the radio bothered me because it was too loud.  Most NT’s don’t like the radio loud either but it isn’t a deal breaker for them.

And my latest halfbakery, basically a tip of the hat to Jeff Raskin, an indicator light for whether an OS is patched, a patch is pending, or it isn’t in the patch pipeline at all and thus insecure and dead in the water.
