So lets get this straight! J.C DID reserve a seat, but someone else was sitting in it. He didn't want to ask that person to move, so sat in another reserved seat, and was asked to move by the rightful owner of the seat, which he did, and ended up with no seat, sitting on the floor. I thought that his party didn't pre book their seats, but it now turns out that they did?!! This tale changes with the telling!!
dj, no one has been unpleasant about your son and dil, just pointed out that their action was their choice, and not the fault of the train company. You do have a tendency to bring your family into conversations, therefore you cannot be surprised if by doing so you provoke a reaction, favourable or otherwise.
