I think that comment overestimated how much people really remember.

That bartender most likely has 3 to 5 worse assholes every shift and dozen usual assholes . He is not going to remember he doesn’t care.

Local non profit after 2 years most likely won’t have the same people and top guys won’t remember all one off volunteers.

Believing any of it having more significance would be attributed to “spotlight effect” in my opinion.
