I was hoping that by September things would largely be back to normal, possibly with social distancing on public transport lasting into early next year, With the current protesting I don't know right now. Hopefully some form of catering will be available towards the end of the year, but I cannot see much changing until 2021.
Somewhat off topic, but what is it actually like 'out there' on the trains? I've not even been as far as Reading, let alone London (which seems a distant memory) since early March. Previously I was in London 4-5 days a week more or less for 20+ years. My department don't foresee even a review on any movement until the end of Q3, my season ticket is long since cashed in.
