As Paul mentioned... There could be 100 different reasons for the clock running down.
Just FYI.. I play a lot with a good friend who does other things while playing, like cooking and cleaning and caring for her kids. She will often miss the clock all together, but I understand and just accept it. I often do other things while playing too, and the same can happen to me, but rarely does.
I doubt many players are letting the clock run down deliberately, but more likely are multi-tasking !!

I am not making up anything it is a fact that there are players who waste time for no reason by running the clock down to the last second on the easiest of shots like tap ins. Most players don't do this but there are some who do. If someone is going to play they should be watching the game instead of sitting there fiddling around with other things then they would know when it is their shot. No one is remotely interested whether you are rolling a smoke or not, no one cares one bit about that. Use some common sense and roll your smoke before you start a game, it is not rocket science. Have a nice day lol.
