Horrible bar in Jakarta

I went to this place a couple of years ago. I was a regular customers coming there for over 5 years. I even sing/played guitar there. They also have a pooltable where i like to play pool(And always for free).
Here the problem started. When I played pool I never ended up paying for the table, since i have played there many times, untill one day.
They count the games I played and the waiter told me I need to pay 5.000 for each game(And i played more then 10). I asked another expat if he also paid. He told me he knew about it.

They never gave me notice anywhere in the place, that you'll be charged for playing pool.
Then the manager came, i asked him why it's not written anywhere, then he gave me a stupid answer: "You never asked".

It's not about the money, but the way they do customers like that should not be tolerated.

I did pay he money, and told him to wipe his ass with it and that he lost one customer. THey don't really care. I will never come to this lowlevel place in my life anymore. THey should burn it down.
