Can anyone explain why they do this?
Just got on a train with my two kids - we joined a lady on her own at a table, she looks daggers at me. I realise it's not fun sharing a table with two young kids but why then sit at a table on your own? You are so much more likely to be joined by a family group! When I am on my own, I always prefer an airline style seat as I am much less likely to be joined by a family.
Is it just the triumph of optimism?
