The weekend warrior game is so different from what the pro's play should there be two sets of rules ? I will give some examples of how most of the games I play with other golfers. On the first tee mulligans can be played. Some groups will let you choose either ball when the mulligan is played and other say if you hit a mulligan you have to play that ball.
Lost ball. When a lost ball cannot be found another ball is thrown down in the area and a one stroke penalty is accessed. Going back to the tee box and hitting your third shot is never done to speed up the game. In the fall when there are leaves every where a ball is thrown down without penalty aka the leaf rule. I have played where a lost ball is deemed a two stroke penalty and a new ball is dropped on the edge of the fairway near the lost balls area.
You get the idea. Should there be two sets of rules since most golfers play like the two examples above ?
