Let me make myself clear, I always thank people. What I did those days was to be mindful and sincere instead of thanking in auto-pilot.

Someone physically and/or verbally attacked you for thanking them? That's the only negative outcome that I can imagine, and what I'm reading when you say "hostility."

Attack seems too strong, but an hostile tone, yes. More than once.

My goal wasn't to be praised, but I did have a goal of actually causing a positive effect on others; I have no interest in "good deeds" that help no one except the performer to feel proud about himself.

Considering that all signs indicated I was actually bothering people, I stopped, as I think anyone should.
