That's all, folks. As soon as I'd taken this, an ice rink lady charged up to me and said "Sorry, luv, can't take photos, it's Child Protection you know."!
Just to clarify matters.
This is untrue. You can take photos of groups of people out of doors when in a public place. Indoors it is up to the proprietor. So, Dear Ice Rink, it's not the Child Protection, it's YOUR own policy which does not permit photography. I suspect someone has got hold of the wrong end of the stick!
