I'm sure it doesn't happen now but I was a guard at Kings Cross in the 1980s and putting their feet up on the desk would be only one of a number of infractions. I vividly remember being at Hornsey station at about midnight and wanting to get back to KX and thumbing a lift from the driver of a Class 47. I got into the cab and the driver was obviously drunk so I was trying to watch the signals while he babbled on. It was only 7 minutes before we arrived but I aged 7 years. When I did route learning to York in the cab of an HST I thought the driver would be doing all kinds of complicated stuff but once we reached Finsbury Park he just opened her up, put his feet up and lit a cigarette.
