Just to be aware - I saw a bunch of young lads standing outside the betting shop near the station this afternoon waiting to be picked up. They each had a box of cheap tea towels etc which they will be trying to sell around Forest Hill homes - hence the term "knockers" usually on the pretext of being a charity or asking for a donation in return for one of these items - it's a well known scam and as old as the hills. The items are not usually worth what is paid for them. When they have blitzed one area they move on to another.
