There is probably a good answer to this but …

On Shabbos, while in the male urinal, I stood next to a guy who was wearing his gartel. I admonished him and said that the gartel was a הכנה for davening. I don’t believe it is necessary today, but I wear one because my Zayda Yidel HaCohen Balbin ע’’ה did (and on Yom Kippur I wear his Gartel, as he passed away on Yom Kippur)

The guy thought and said, “you know, you’re right”

Anyway, when I was younger and devoted some time each day to Mishna Brura, I remember being inspired by his words regarding wearing Tzitzis out, as opposed to in. I don’t include the uncouth manner of some who wear their shirts out of their pants as well today, something I don’t understand unless one wears a Kapote covering it (I see boys from the local Yeshiva all dressed like that, and personally I don’t agree with that practice).

Getting back to the Mishna Brura, in his usual way (not Litvish) of quoting all opinions he wrote very strongly that one should wear the Tzitzis out, as if he was a proud member of Hashem’s army. That was when I was in Kerem B’Yavneh. From that time on, I followed the Mishna Brura. (Ironically, the major Posek was actually the Aruch Hashulchan, but he was then considered controversial for very bad reasons by Hungarians, but in Lita and elsewhere they followed the Aruch Hashulchan).

Anyway, to my question. I don’t wear a suit jacket to work. My Tzitzis have always hung visibly at University. I am sure it didn’t help, but I don’t and didn’t care. I wear a shirt and pants, generally. In winter its warm and in summer it’s cool. It’s natural.  I walked into the bathroom, and went to the urinal to do what men do. In Universities, they don’t exactly smell “wonderful” once the students are in season. I left the Urinal and asked myself for the first time (I don’t know why) whether I should have tucked in my tzitzis before entering. At the end of the day, although the Mitzvah of Tzitzis is not a Chovas Gavro but a Chovas Cheftza, the Tzitzis themselves are M’aaseh Mitzvah. I haven’t looked to see  if this has been discussed anywhere (many Poskim/Haredim wear jackets and Yibitzes which cover the Tzitzis).

For Sephardim who follow the Zohar and Ari, this isn’t a question because they aren’t allowed to wear their Tzitzis out from memory because it’s considered Yuharo (showing off).

Am I asking a silly question?

PS. I’ve also mentioned to Meshichisten who have the advertisement on their Yarmulka that they should turn it inside out before entering a bathroom in my opinion.
