Booked a forward facing table seat as have some work to do on my way to a meeting. Arrived at seat to find woman with dog under the table who got on at the same station. Went to take my seat and she said “sorry you can’t sit there, I need room for the dog”. Dog does not have anything on it to identify it as a working dog. Surely she should have been sitting in the unbooked area if she wanted to hog all the seats?
