Some time back I taught a one board bird house project class. I had a number of students agree to attend and I showed up with 5 boards, which I bought for the class. They were pine and were pretty cheap, but still I bought them for the students. Drove over to Home Depot put them on my credit card, etc.
Only one student showed up. Not even the three necessary for honorarium. I taught the class to the one student who did show because he seemed very interested in the class.
I prepped for the class, bought the materials, showed up to teach and I didn't have enough for a quorum. It was very frustrating.
I wasn't teaching just for the honorarium, but teachers shouldn't have to deal with no shows and lose an honorarium because of the students not showing.
I'm with @uglyknees:
In any case, I think the system is much better now and hopefully will improve even more over time.
