In a brief recall such as the parent post, certain details would seem either superfluous or meaningful if they don't appear to relate to the topic.
If you mentioned that the guy at the counter of the CVS was wearing a baseball cap, we would wonder why that was a significant detail, or maybe "what team was on the cap".
Saying someone had a hijab is clearly leading with some meaning, but the post didn't go into that detail. I can only guess that it implied something related to Muslims; but I don't even know. They didn't expand on that. So we are left to wonder WHY they mentioned it.
My interpretation was simply painting the picture of who helped him, and not commentary about muslim beliefs.
As another commenter said—humanizing the part of the locked deodorant, and that they did not mind because at the end of the day “we’re all in this together.”
