Now is not the time for advice on communication, but I can't help but comment on this, sorry. Take this with a grain of salt because I wasn't in the room. Should the manager be able to handle your questions better? Yes. But, consider this rhetorical question, was your aim to embarrass the manager or improve the situation? Even though you were presented with something ridiculous, from the manager's perspective, you embarrassed him in front of his reports. Criticizing someone (or an extension of them such as their work) in a group setting can be very destructive. In a situation like that, I recommend talking to the manager one-on-one afterwards. That gives the manager the opportunity to do something that fixes this and to be a good manager that listens to his employees and comes up with incentives that might actually work. If the manager doesn't want that outcome, don't waste your time there. Your manager might be childish and unprofessional. He might just lack the empathy required to understand your perspective without it being explained to him. If he is the former, and you don't want to get fired, you have to act in a way that is acceptable to someone childish and unprofessional. I think a good manager would handle your points and questions and give you some kind of response whether it be 1) I'll look into fixing this or 2) sorry, I can't fix this. They say good managers are hard to find.
