I dont think it made the room owners lazy. Economics of a pool hall have changed. If you run a room with 9 foot tables the income needed per table is not compatible with what MOST players want to spend. Rent alone dictates most table rates should be about $20/hour. Most players will not pay $20/ hour to play pool. So what does an owner do? He puts in candy bars for sale. He puts in poker machines. He raises the prices of beer. He puts in scratch off tickets. He puts in a couple dart machines. He puts in a jukebox.
Yes, owners put in all the things that take away from what "old timers" think of as a REAL pool hall. If every guy that walked into a pool room paying $12,000 a month rent would grab a tray of balls and gladly pay $35/hour for pool, most owners wouldnt care about poker machines. Life in a pool hall doesnt work that way. Everyone wants a CHEAP table rate. We are charging $1.80 / 9 foot tables with no bar. We still have plenty of tables open every day. We are still losing money. There are simply not enough players to support pool any more.
