anon german, I think I'm right in assuming that PhD students here aren't in it for the pop star salary! The point is that once you have been offered a certain amount for a stipend you budget according to how much money you're told you'll get. So, it does become a big disappointment when it doesn't work out that way. Also, some people have more financial commitments to meet than others - particularly where they have had to borrow a lot to complete their undergraduate and/or masters degrees.
