Off Topic: I always use to charge people double if there bags where on the seats, they would question the price and i would say its because your blocking a seat. I remember an entire family where going on holiday and took up 2 sets of tables, 1 for them and 1 for all there luggage. Got told to shift it, weren't happy.
On Topic: EDB>GLSW trains only have 18 1st class seats out of a 4/6 carriage train so the ratio for 1st/STD isn't a problem up here.
