There is a social psychology thing called a "social breach experiment."
https://en.wikipedia.org/wiki/Breaching_experiment
In such an experiment, the experimenter purposefully makes a social error, such as walking up to someone and saying "goodbye" instead of saying "hello" or paying for lunch with nothing but pennies when there is a long line behind them. The purpose is to observe the reaction of others when the social error is made.
Typical reactions to these errors are to freeze, to get away from the erroneous person, to FIGHT them, and sometimes to laugh.
The reaction is never to explain the error and ask them not to do it again. You see how if this WAS a natural neurotypical reaction to a social error, an atypical person, such as a person on the autism spectrum, would find social life much easier to navigate.
