OK that is a fair comment. Like i say no other Championship clubs do this but lets give the club the benefit of the doubt that they are going above and beyond other clubs (despite the high levels of anti social behaviour going on in thar area).You may mock my comment on safe guarding, but I know that it's a reason why some other clubs don't allow 'unaccompanied adults' into family areas.
Perhaps making people buy in person at the Boro ticket office is a way to weed out oddballs (for want of a better word)?
If that is the case why wouldn't they make this clear this is the way to purchase these tickets? Instead of just shading them out as unavailable.
