But there aren't any "retail opportunities" in the underground labyrinth
connecting the tube tunnels to the barriers.

But there's a vast number connecting the Thameslink platforms and for
that matter the Midland Main Line platforms with the tube system,

You can miss most of them from the MML platforms if you take what's
perhaps the shortest route in any case - along the mezzanine to the
'Kissing couple' then down a fairly long staircase to the Western Ticket
Hall.

whether you choose to go the length of the old St.Pancras station or
across in the King's Cross direction and then down.

Including the Farmers Market under the St Pancras departure board which
seems to be an upmarket deli with the brand name "Farmers Market",
rather than an actual market with farmers selling things.
