I'm not averse to travelling a certain distance, but there has been something of a drought in the north-east generally for quite a while and the same can be said with black service providers. Yes, there are occasions where someone pops up, but there are quite a few of those that have been suspect, have reviewed badly, or indeed both.
What I'm trying to say is yes, I'd love a decent, and genuine, Indian/Pakistani WG to stick round for a reasonable bit of time. That this isn't the case more often suggests that the demand maybe isn't there, or can't be guaranteed in this area, whilst other areas can guarantee it, so they benefit instead.
