Back in the early 1980's I helped to take a group (about 40) of inner-city Halifax, Muslim kids for a day out walking up the hills to the moors with a break at the topmost pub's beer-garden for them to eat sandwiches, purchase (soft) drinks - so paying our way - and the licensee was most impressed with their behaviour and how tidy we left the site. In fact he wrote to the school to say so.
The girls, of course, turned up in floaty shalwar-kmeeze and sandals, so lots of grumbles, but they all - ALL - enjoyed the experience and knew that the countryside was theirs to enjoy and respect. I'm willing to bet that almost every child gets this sort of opportunity (especially in the last week of the Summer terms) so any prohibition and hesitation has to be manufactured by the minority communities as yet another source of discord.
