A friend of mine, well a guy I have a pint or three with now and then, has just taken early retirement form being a "revenue assurance officer" for SWT. He regularly worked at Richmond on the barriers. Reason being, he just could not handle the grief anymore. Not only from aggressive passengers, but also the Hitler like new team members. Plus the increased chasing of monthly targets by the management team. According to him all good sense had gone out the window.
