When I was a student at Purdue in 1955, the pastor at the student parish was referred to as "high speed Heilman." He could get through a Sunday Mass with smoke, and Benediction, in 45 minutes. He had two teams of altar boys. While he was reading the Last Gospel, one team would be stripping the altar for Benediction, while the other would be bringing out the Benediction robes and the Monstrance.
I have no idea whether he "cut corners" or not.
That kind of stuff really bugs me. Are people really so busy that they can't take an hour out of their time for God. I've been to Mass a couple of times where the priest and/or the parishoners seemed like they had someplace better to be, and it felt like it was a fast food drive through service, McMass.
