Not knowing all the appropriate social responses to some extent is "ASD-normal".
There are a lot of separate cases, and everyone else (NTs) started learning them at about the same time as they were learning to speak.
Remember cases that turned out strangely, and find out what to do.
Note that bullying is something else - don't mix errors in "NT-normal" behavior and bullying.
You both described incidents where you waited for someone without informing them you were there. This counts as "creepy" behavior. Different people have different responses to that, rarely 100% rational, and the specific response will depend on whether they were already stressed (Fay's example) or working (grommet's). Either way it's better to avoid giving that impression.
Where I live (different language, but I think it's the same in most English-speaking countries):
* If you're blocked, you say "excuse me" calmly, politely, and at normal volume. They will either ask you to wait a few seconds (perhaps to finish something) or immediately let you past.
Annoyance in your tone of voice counts as rudeness, and they may not be as polite or as accommodating.
* If you want to help, you
ask. "Can I help you with that?" works well, but any similar polite formulation that's semantically equivalent is also ok. Again, tone is important.
The reason tone matters (and should be trained if you have issues managing it) is that exactly the same words in the wrong tone are regularly used (e.g. by "Karens/Kens") in a passive aggressive way.
Every NT listens for (and reads for /lol) that kind of thing continuously, and many will react negatively ... which changes the "rules".
The protocols for being on either side of a snarky conversation are different, and more complicated than simple politeness.
Bullying is more complicated again, and depends on context. In general I wouldn't trust online advice
anywhere on how to deal with it. It's
very situational, so there's no general method for dealing with it.
Note that bullying is
not "NT-normal", but avoiding conflict is.
Bullies select their targets, and carefully select the places the times and places they apply their methods.
