Becoming a grumpy old man?

Just on our first outing of the season at Lochside, Forfar and have found the behaviour of some fellow members totally unacceptable. We had 2 lots staying together who decided that our pitch was the shortest possible route to the toilet block and would even stop outside our van to chat to each other.

My wife tried to speak to them about it and they just ignored her which was about par for their behaviour. We are normally very easy come, easy go but the people on pitches 24 & 25 really rattled our cages.

Am I turning into a grumpy old man or is this considered acceptable behaviour?
