I had a hell of a day today. I needed to be in central London for an event lasting a couple of hours, sandwiched between two 4hr+ journeys on what was one of the hottest days on record.

The saving grace? Wifi on the train. For free, today, as part of an introductory offer, but even when you’re paying for it, you have to admit the prices aren’t too horrendous (especially the 24hr rate if you’re doing LONG journeys).

What I’d like someone to explain to me now, please, is how come I can have wifi on a train moving at 80mph, but coffee shops think it’s too much to offer it?
