It’s a pool table that will serve its purpose of casual players having a good time. Not sure why this gets so much negativity from folks who complain that pool isn’t more popular. At least it’s not a foosball or ping pong table.
It’s counterproductive to spend time thinking about shots that have already happened, which have no bearing on the current situation on the table. The only person it helps is your opponent.
How is wasting someone else’s time not rude?
If you are doing a solo session then by all means play as slowly as you want. In a league night your actions have an impact on other people whether you like it or not. Pretending otherwise is selfish.
