Back in July, I and others were shoo’d out of the first class in the driving vehicle, into the limited seating of the composite, where consequently it wasn’t possible to maintain the advised level of social distancing. A few passengers with first class tickets, observing the situation, opted to sit in Standard which was relatively quiet. This was a west of England service.
For this reason and others (no catering, no lounges) I’ve given-up on GWR first class for the time being. I find the Standard seating in the 800s to be comfortable (minority opinion, I know), and there’s a great deal of it in 10-car formations.
