Yes, thinking I've bought a ticket when I haven't
actually bought it and have no record to back up
my belief i've bought it would be a pain.

That's why i always have the receipt mailed to me,
not just the link to a receipt.
With the link to receipt, if I could click one day and
see bought, and click a week later and see
reserved, not purchased, I would be at a loss.

This week's problems were in the other direction, though,
with unpurchased tickets shown as purchased.
