I once knew an Indult priest (not an FSSP) who sped thru Mass so quickly that you literally might miss the Elevation of the Sacred Host if you blinked. It was so disconcerting and so fundamentally disturbing. There was not a second - not even one second - to adore Our Lord at the elevation.
Then he sped thru the Leonine prayers at the end of Mass so fast the faithful couldn't even keep up, and he would start the next Hail Mary before they were done reciting the response part.
I wanted to say something to him after, but I didn't. I regret that now. He had a very badly ingrained habit.
