Tested a higher price on the next five course buyers

I raised the price by 40% for the next five people who enquired, and told them why: fewer seats, more of my time in the feedback rounds. Two bought without blinking, one asked for the old price and I said no, two went quiet. Five people is not a sample, I know that. But the two who bought never mentioned the money at all, and that is the first time that has happened.
