On the last day of Pesach, an unmarried guy got maftir. He was wearing a tallis, but only because he was also the baal koreh.
An unmarried guy got hagbah (and put on a tallis for it). A married guy got gelilah.
I once bought hagbah & gelilah in shul on Yom Tov and gave gelilah to my grandfather. I would have given him hagbah, but he was in his mid 80s and wasn’t able to do hagbah anymore. I tried to get him an aliyah, but I was a bachur, and couldn’t afford it.
I don’t think the married guy in my shul yesterday or my grandfather were nebs. I think popa is the biggest neb, for making a joke out of something which is a real kibbud. He comes here pretending to be a Rabbi and creates bad trolling threads. I feel bad for his wife and kids.
