Hi All

I was practising at the putting area (10 holes) when 2 kids supervised by their father started to play each holes against each other. They were faster than me as I was hitting 3 balls per hole and trying to make it as hard for myself as possible. But they just happily started playing the hole while I was putting it and I had to stop until they left to carry on as they were in the way.
Is it ok for them to barge in like that? Is there rules on the putting area? I have been at times were it has been a lot busier and it never happened. We just go to the next available hole and carry on. Am I allowed to play several balls? My instructor told me I should do so to practise.

Thank you
