Those examples aren't something a person needs help on, I think that's the difference. I can't spot my own lift. I can't teach myself what a certain machine does if I don't even know what it's called. I can't understand a new lift I haven't seen before without asking the person doing it what it is and a little about it.

Ask people for help where help is actually needed, not to act as your servant cleaning up behind you.

The OP of this thread didn't specify the nature of the favours, just gave general advice which I think is not helpful.
