I play with a good friend who has a floating " mulligan " system. It can only be used on the 1st and10th hole tees. Then the next time it can be used anywhere only 1 time per round, ect. There is about 8 variations. I don't use Mulli's but was just curious as to see if anybody else runs across this situation. I just let it go , we play just for run and a chance to get together with friends.
