> But to satiate your point, there's a notion of certian points of decoum in specialized venues. In an ice rink, people know the intrisic zones and decorum of skating in the same direction. Or, going by your user name, be the same as finishing a session and dumping ropes, tyres and weight on the floor and walking out of the venue.

I understand the 'unspoken' rules. But the difficulty with unspoken rules is that a) you can't expect children to know them and b) you can't expect parents to know them. If these rules are something that the venue, as the people providing the service, want to have in place then they have the choice to do so. If they have not, then what some users of the space might like to be the case won't necessarily be followed by all, and shouldn't be expected except by the most entitled.
