this has puzzled me for some time.
at least once a year we travel by TGV. I have never been able to buy TGV tickets without booking a seat at the same time (nor wanted to...).
however, almost without fail on the return journey (when we're not getting on at the first station on the route) there is already someone sitting in our seats. of course they move when we ask them to (although they often take their time about it, leaving us with no choice, but to block the aisle), but why haven't they got seats booked too? how have they even managed this?
that is all. thanks.
