The thing I never got used to in our old church was the Asperges at the Easter Vigil. I stood on the front left of the choir, behind the altar, and we would be singing the "Vidi Aquam" (I told you it was a High church) which is fairly difficult chant (especially when our choirmaster has the men and women singing different parts in some spots and unison in others) when all of a sudden I would get a face full of water because I was on the front row. My copy of the "Vidi Aquam" actually has water spots all over it, I got nailed every year with what seemed like quarts of holy water.
In our new church, the choir sings from the choir loft/gallery at the rear of the church, so we don't get any holy water at all . . . .<< sniff >> For the Easter Triduum we are downstairs, because we lead the procession of the Blessed Sacrament from the Tabernacle to the Chapel of Repose . . . right in front of the thurifer . . . so we get well and truly censed.
If you think of the floor of the church as laid out in a crucifix shape, we are singing where the Lord's right hand would have been. There's only 8 of us. There's room for 16 (3 pews, four on the left, two on the right, the pipes of the organ that was installed after this was all set up blocking the bottom pew on the right hand side). The front pew is about 12 feet from the Communion rail (apparently these are gone from a lot of RCC churches now?). Charlie make sure we get our share.
I've been a Cubmaster or Scoutmaster for the last 12 years, so singing in smoke is no biggie for me. But we've got a couple of people with allergies, so they need ventilation. The prevailing wind blows from behind us, into the church, so opening the windows usually fixes things.
And when it comes time for Holy water, our priest has got a good right arm; he gets us pretty good.
