The Disappearing Dinar

A bill of 30 dinars is paid by the three men, each putting up 10 dinars. It turns out that there was an error; the bill was only 25 dinars. They get back 5 dinars; each takes 1 dinar, and the remaining 2 dinars are given to the slave who served them.
However, someone finds this strange, because now each has paid 9 dinars making a total of 27 dinars. Adding in the 2 dinars given to the slave only makes 29 dinars. How did 1 dinar disappear?

Seven

Seven are the gates of hell
Seven are the days of the week
Seven wise men of Greece
Seven the seas that cover the earth
Seven the planets, and seven
The wonders of the world

Seventh Heaven

21 identical casks of wine, of which 7 full, 7 half full, and 7 empty, are to be divided among three men. Each should receive the same amount of wine and the same number of casks, without opening them.

How to do this?
