I worked at a convenience store. My dad instilled in me the dangers about gambling. He used to own a store that had poker machines. One day he saw a man come in and spend his entire paycheck he just cashed next door in his machine. The guilt overcame him and he got rid of the machines.
While I have no problem with people spending a dollar here and there, it pains me to see people spend a lot of money on things like the three digit/four digit number drawings, especially when it was clear they really didn't have the money to be spending on it. I still don't play the lottery, even after leaving the JW's.
Although it does make me wonder why JW's are allowed to work at convenience stores when they sell cigarettes and lottery, but can't work at a casino.
