I had one of those “don’t spend more than 30 minutes on it; but …” tasks at work. I HATE it when people tell me to waste my time. If it could be done in 30 minutes I would have already done it! Then I spent an hour that I didn’t really have explaining why I wasn’t able to do what they wanted in such a short amount of time. I don’t mind if people want/need for me to work on something else when I’m already super busy. But it’s very irritating when they tell me not to spend too much time on something and then get mad and don’t like the result.
