Find it odd to call F 'Public Transport' in the true sense but it is a shared space.,

The same thing applies in F to all ages including children under your care
Having wealth and the abilty to aquire an F ticket doesn't give you the right to behave and do what you want

Recently stayed at an expensive resort hotel where kids of a large party were allowed to roam and scream and run ferrel at all times of the day ; The parents drank their wine and turned a blind eye...

In my view completely destroyed the ambience of the place
