Make the staff play after work!
I'll have a wee chat with some of my friends in the far flung corners of this country and see what's about!
What sort of distance are you happy with travelling?
//edit:
A very quick Google suggests Shire Games (shop in Stoke) seem to run 2 nights a week - 1 at a pub and the other at their shop, linky!
Also Staffordshire Wargamers maybe worth a punt!
Just found Geekbox just down the road from the shop too by the looks of things!
