What if somebody wishes to cancel after hearing the 3 weeks as opposed to 2 weeks?

For e.g. if they're travelling, etc. Could result in loss of revenue as well.

I'd actually see that as a positive thing; too much money is wasted on the sunk cost fallacy, and having the guts to cancel a project if it goes too far over time / budget is rare enough.

I would argue that it is impossible to form any conclusions here without knowing what the exact specific situation is, but of course what you described is plausible.
