When I was a small child, one of my daily assignments was to move the tee markers--by hand--which I did with great enthusiasm. (This was before I learned to nudge them along with the tee mower.)
For some mysterious reason, on Saturday mornings, the markers sometimes found their way back to their original slap worn-out position and the blame landed on me. Upon further investigation, I discovered the culprits: Gamblers.
Golfers who played for money wanted the course set up to their advantage, especially when they had invited
pigeons guests to play.
When I indignantly placed the markers back in a less chewed up spot, the blowback from the gamblers was fairly severe and the blame landed on me. (Probably because Dad was one of the gamblers.)
Later in life, I learned the proper, more diplomatic way to solve the problem of golfers who move tee markers, as explained in the following short film: How To Diplomatically Deal With Golfers Who Move Tee Markers
