Nope, this isn’t the way it should be, and you shouldn’t have to waste time in a line that never ends up going anywhere. I think we all agree on that.
But the fact of the matter is, if you want to be guaranteed confession, you’re going to have to be the one to make it happen. If you go right to calling the bishop, the first thing he’s going to want to know is what else have you done to solve the problem at the local level. Have you graciously (and more than once) called the priest to let him know that scheduled times are not working out? Have you asked him what he thinks could be done? I wouldn’t assume he’s BSing. From what I’ve read on these boards, there are a lot of people who don’t know that you’re supposed to be in and out quickly during scheduled times, and just get right down to business immediately.
The guy sounds pretty thoughtless, and it may get you nowhere to talk to him, but I know for sure that if you approach him before you can do it without anger, he’s going to resist you. He’ll tell himself you’re just another whiny crank. Invite him to be part of the solution. If he won’t do it, then you’ll need to find another way, another parish, something.
And then you will be justified in going to your bishop, because you will have done everything you could at the parish level.
