Yes I've visited this shop. I agree that it's a point of discussion, whether it's a convenience store or a supermarket. Mostly I did it because I find it rather annoying that a shop of this scale is not found on OpenFietsMap as a supermarket.
Ouch, thats mapping for the renderer. It is a problem wich exists all over the UK, because a lot of shops, wich are small, but welprovided, can't be found as supermarket. If you want to revert it, be my guest.
More important than this, is my remark in the center of Telford.
