First of all. Pool players, be they professional or not are really not as rich as you think they are. They would certainly not like to throw away money if they think that the odds are stacked up against them.
Moreover his visit to that pool hall was not a publicized event. I didnt even know that he was going to be there as neither did many people. I would have certainly throw him a couple of 50s to have a shot at him.
Further more, last weekend was a busy one with the national finals and KK was going to be playing in the finals of an 8 ball team event. I think it would be most irresponsible of him to be putting his focus on anywhere but the team event as he is also the captain of the team.
Finally, i do not know which day those guys turn up at that pool hall but if I read the promotional posters correctly, any money get that is going to occur would have to be after Alcano has finish with his promotional duties which would be past midnight.
Our national players are people too. Some could hardly hang on to a decent job. Alot of sacrificed has to be made. Spending almost all the time and money that they have just trying to make it work.
So i say. if they really think they could not afford to lose then just walk away from it. There is really no shame in admitting that you are not good enough yet. There will come a time when the tables will be turned.
