In
Britain, a 'totter' is also a person who is licensed to
trawl through
rubbish dumps and
recycling centres for discarded items or material that they can sell for
scrap or repair to use or sell on. Such an occupation is known as '
totting'.
Although not a common sight, totters perform a similar function to the increasingly-rare rag and bone man.
