Not so much cheating however there was an incident at our club a few months back were a 4 ball were pottering out, everything was amicable by all accounts and chatting between greens and tees. During one particular chat the first player tee'd up, hit it straight down the middle only to get pulled up by one of his PP for going off the yellows and not the whites. The guy wasn't concentrating and there isn't a huge difference at ours between yellow and white so it's not that hard to do. It all kicked off because whilst the guy who played fully admitted to being in the wrong and it being his mistake the PP who pulled him up had realised his mistake and wanted to see if he'd realise before playing the shot. He didn't.
Obviously it is ultimately the players fault as he should have played off the correct tee's what sort of a person are you if you watch someone unintentionally doing something like that and you don't have a quick word to stop them before it's too late.
We had a similar thing happen earlier this year. One of our regular 4ball was teeing it up on a par three. Just as he started his swing another of the group pointed to the tee indicating something was wrong. From my angle I couldn't see but walked round after the shot and saw that he teed it up a good foot in front of the white tee blocks. I then pointed this out to the player but felt guilty as he probably thought I had let him do it before teeing off even though I was not aware until in had happened.
