Commuters arriving at London Bridge station on Monday were surprised to find their journey less stressful than usual.
A brigade of helpers in blue and yellow boiler suits was on hand to assist rush-hour travellers with daily tasks from carrying heavy bags to opening doors and giving directions.
"An extraordinary 80 percent of people want to volunteer but don't know where to start," said John Barkus, director of Volunteer Centre Southwark. "Giving just a little bit of your time can have a big influence on other people's lives. Volunteering is a great way to meet people, have fun and support a good cause. And getting involved is simple through your local Volunteer Centre."
