The underground platform was muggy and crowded at Euston.
A train drew in and we surged forwards towards the doors.
A large and fierce woman pushed straight to the front of the crowd, using her tartan shopping trolley to barge through so she was in premier position to be me-first into the carriage.
The doors opened.
There stood a large and fierce man, with an identical tartan shopping trolley which he used to shove her out of the way so he could get off.
Politely and triumphantly, we entered the carriage in our original order.
