Have You Ever Seen a Player Call the Clock on Themselves at the Poker Table?

I happily admit that I am a slow player at the table. I have never and will never call the clock on someone else. Some decisions can take a long time and it’s OK for someone to take their time. However, call the clock on myself? That’s not happening. I like to keep the game moving as best I can, but if a decision needs time then it needs time.
