Toilets are useful immediately (speaking from experience!)

Tables are useful even on short trips of a few minutes; e.g. I usually have a notebook and pen in my pocket, and writing much easier on a table (even the little fold-out ones, if I can't get a seat at the proper tables).

I often eat on trains; though I admittedly tend to avoid the dining options, since it's much cheaper to bring my own food and eat my seat's table (fold-out or otherwise). If I'm with others, we can also drink alcohol together, without a "designated driver" having to abstain.
