It is rude and selfish to make a general confession when people are standing in line for confession and cant go because you made a 5 minute general confession. Then these poor people who travelled far can’t receive communion. I don’t blame any priest for being impatient with you. This happens often at various chapels. It is sinful to abuse the confessional each week.
^^^This, couldn't agree more.
It is only intuitive to think that confession needs to be, as AA would put it, "a searching, fearless moral inventory", that takes as long as it has to take, but as a practical matter, the rule in a quotidian confessional line needs to be "be brief, be bold, and be gone". (And a general confession could take far longer than five minutes.) If you need more time than that, make arrangements with the priest outside of regular confessional hours, which in "flying priest" chapel situations, might be a "big ask", but the point should be clear, don't hog the confessional and keep the people behind you from being able to make their confessions as well. I've found that modern people, even among traditionalists, don't know how to keep their confessions brief. I suspect this might be from the pop-culture notion of "confessional as psychiatrist's couch". Two different things.
The "long game" solution is more vocations, more priests, and more opportunities to go to confession in the first place.
And full disclosure, I have never had to avail myself of AA, never had that problem, I hardly ever even take a drink of alcohol, but I have had people close to me whom AA tried to help, one family member, they couldn't reach, he died drunk on his couch.
