I have seen bad first aid training (and almost any other kind of training) at open courses (where the attendees chose to attend), as well. I've often seen someone teaching who just knows what's in the book (they were taught to teach a course). Whether it's mandatory or not doesn't seem to much change the nature of the instructor, but the nature of the attendees...and that latter, not so much, either. I get people attending public seminars on business topics who clearly decided before they walked in that this was just a chance to get out of work...and they paid (or talked someone else in to paying) $200 for that.
