I do find it rude usually and I would never use it for that reason; most people I know/do business with would literally tell me to suck a pipe no matter how the request is phrased. If the meeting is important, I'll make time no matter what you suggest (and vice-versa, otherwise you seem to think it's not important and we don't have the meeting); if it's not then why are we meeting in the first place? But it is a clear power-play for most people who send me that stuff; clearly they want to show how important they are. Some of them have told me so over a (traditionally planned) beer.

Disclaimer; I try to have as little meetings as possible outside 1-1 and team meetings which are ad hoc mostly when we are chatting anyway about something work.
