UT, eh? 18 years you say? 17 years there myself, more or less. I especially enjoy the meeting of the eyes with fellow like minded folks while the Mormons speak in their Mormon inflections and tones and their distinct defeated sounding "sing song" droning, as they go through the motions of reciting incantations to their Heavenly Blah Blah Blah.
I also live by the "my house my rules" guideline for civil society, and completely avoid the houses of lunatics altogether, except for those exceptionally rare times, usually after a death. I am polite, and patient, and quiet. But I do not bow, kneel, recite pledges, stand, sing, etc... i.e. I behave like a civilized person in polite company. Thing about Mormons is, they don't realize they are testing your patience or violating your boundaries, and the words "no" and "no thanks" and "keep it you yourself" do not compute to them.
The secular side of the family was granted permission to visit my young "elder" brother on his mission in Long Beach in '02, and I did completely snap at him and his companion over lunch in a restaurant one day. My mum and grandma were bending over backwards to accommodate his new found Mormon crap out of fear of losing him forever... Anyway, lunch was on my mum, and the tab was gonna be a astronomical... And as the food came out, the "elders" decided to, uninvited mind you, give a blessing. I bit my tongue... Until they got to the part where they were thanking "Heavenly Father" "for this meal" etc... I went nuclear, I interrupted and gave them a thrashing. I told them they needed to thank Mum for this meal, and not their invisible made up celestial sky daddy, and how dare they force their visitors into their bullshit incantations in a public and neutral place, and how detestable and rude and mindless it was to just assume that we were willing to suffer it, and how insulting that was. Their Mormon bullshit, mind you, we actually find outrageous and unequivocally detestable and abhorrent. The "elders" went to find their own table, and I was shot daggers from my mum as she went to join them, but a thankful pat on the back came from my grandmother, who's patience had been long suffering with the Mormons, and my baby brother patted me on the shoulder too; he had had enough as well (the day before the three of them were trapped in the LA Temple visitor center, in a high pressure sales situation with the "elders" and a dozen sisters, and weren't allowed to leave the room for three hours... Followed by two more hours of videos and more videos, and more high pressure mobbing and psychological torture. They were frayed after that. I knew better... I wandered around the grounds chain smoking instead).
Hmm. What do I do that is customary, generally?... I guess I remove my hat in the presence of survivors of the deceased, out of respect for the survivors. That's just a cultural norm, general etiquette. Why other men, pious god fearing men, remove their hats is beyond me, some kind of show of piety I think. But I also take my hat off when I formally enter a host's building, private or public, because that's just good manners. Wait, I don't really wear hats anymore. Used to. Not ball caps, but real hats. Oh, in the winter, in UT, caps are necessary, IMO. I'm fine with people saying "bless you" when I sneeze. I, however, say gesundheit. I'm pretty mellow generally, and only really get upset when I feel like I'm being put upon, in a high pressure sales environment (cult recruiting or obnoxious religious people pushing their wares on me, or when new agers or PoMos start dribbling their brains everywhere and I can't find a polite moment to excuse myself.), or when I feel like my physical safety is at risk for not complying. I actually go pretend to take a piss during creepy loyalty oaths to flags and anthems when I feel especially threatened by the mob around me.
I do, however, stand up to conservatives, GOPers, wingers, fundies, hate radio enthusiasts and all manner of bullies at all hours and in all places. As well as libertarians when their special pet ideologies start to impair their grasp on reality, which is when their libertarianism begins to grate my nerves. But this is neither here nor there.
Give us back Shatner and we'll talk. 
I will totally go stuff him in a sack and rough him up a bit... Well, a little bit more than a bit, you understand, and haul him to the border.
