Yes. It does matter alot who you speak to. Before going to Britannia cadet selection a few years ago (which I didn't get!) I managed to get the Holmes Chapel manager to agree to lending me 15000 pounds unsecured if I got on the course.
That pales into insignificance compared to the amount being lent to, for example, the CTC cadets unsecured. The level of selection that both Britannia and CTC use may have something to do with that though...
