Unique Playing Conditions

The same frequent reader as in the last post had alerted me to the following item in Davar's chess column, March 23, 1956, p. 7 (found by the superb historical Jewish press database):

In the chess championship of the Kibbutzim Union (איחוד הקיבוצים), to take place in April 1956 in the Givat Haim Ihud kibbutz, there is a curious condition: every participant must work in Givat Haim Ihud's collective farm (משק) four hours every day, to cover the tournament's expenses.

Has there ever been a similar "entry fee" in any other chess tournament?
