might it not have been simpler for you to wait for your friend in the cafe if all the sofas were occupied?

If toys were strewn all over the main walkway, that's one thing, but the play area, in my view, is in the best possible location as it is behind the sofas, so not in anyone's way (and it's up to parents to make sure their children don't cause an obstruction) - as for the suggestion that the play area be in the cafe - why? that seems to me to be the worst place for it as all that'll happen is kids get under the feet of people carrying hot drinks - hardly an ideal combination!

I'm with you on the nappy point though - that's grim and certainly not the staff's responsibility to clear up!
