Leyton tube about 8pm Saturday night.

Hope there weren't too many pre-pay people going through...

Are you certain the readers were off? The gates can be set to open but
wouldn't normally be powered down unless there's a fault.

Absolutely. No lights and no reaction. (I tried briefly.)

In fact, when I got out at South Woodford, I didn't understand why the
machine's "View Oyster Usage" option didn't show that I had just come
from Leyton. Later I remembered it was because the machines were off, so
the entire journey didn't exist.

For what it's worth, I have a season Oyster so didn't stop to question
it. Then, as it happened, I forgot I was going out of my zone without
pre-pay.

When I got to South Woodford, I couldn't get out of course, so rather
than even making me pay an extension, the 2 SAs kindly let me out for
free (perhaps cos we both talked the same Oyster jargon :-), and I
promised to go and put some pre-pay on to get back in later on.

However, if I HAD had Pre-pay on the Oyster, what would have happened
given that I had no entry recorded? Just an unresolved journey or a
charge of how much on the pre-pay?

If you had no Pre Pay and went out of Zone you'd have a debit of £1.00
showing.

So it would assume I had started in Z1-3 (my season)? So if a Z6-D gate
had been off, I would have only paid £1 to get out in Z4, since it would
have assumed I came in in Z1-3?

On the way back you'd need to put £2.00 for the cost of two
extensions (assuming you have 1 - 2)

Oh yeah, getting back would not be a problem - I mean the extension
calculator didn't know where I got on in this case, so I am just
wondering how it would guess where I got on (and what it would guess).
