It doesn't do too badly these days I think - the relatively new (West?) Cornish Pasty Stand and Starbucks, added to the pub, Smiths, Upper Crust and Pumpkin offer a fairly decent return given the awkward passenger layout. Couple that with the amenities in the Fishergate Centre and there's not much else you could hope for.
Something needs to be done with the 1/2 and 5/6 islands though, both are awful to wait on and the narrow width is unsuited for the large flows they handle, especially when the VT services use 6 and everyone in Western civilisation descends onto 1 for Blackpool in high summer. If removing the Up & Down Goods Loop doesn't have an adverse impact on operations, then I would back calls to extend 5/6 over the existing formation and effectively combine platform 6 and 7. I would also probably back something that moves the booking hall and main concourse to the northeastern edge of the station, getting rid of the awkward three entrance system at present and allowing for ticket gating.
