They said they can only upgrade Travelcards that aren't valid on HS1.
By which they mean say "Not HS1" - if it says "Any Permitted" then
it's also not valid on HS1, but can't be upgraded. (Everyone
following this?)

HS1 is not part of the Zones (same as, say, Heathrow Express), so I
think they are confused.

Does that mean there's actually no such thing as an "&HS1" Travelcard?

If they'd said HS1 was outside the zones (which now you mention it I
probably know) it would have made the conversation much simpler.

The route on a Travelcard refers to use outside the Zones.

So what they mean is they can upgrade "not HS1" outboundary Travelcards
from that side of things.

It's not so much an upgrade, as a supplement for one ride on the HS1.
Maybe it *is* just the same as buying a new ticket?
