BBC News - 'Chuggers' or face-to-face street fundraisers?
"According to the Public Fundraising Regulatory Association (PFRA), the method brings in up to 600,000 new regular donations each year and donors recruited face-to-face are worth £120m annually to good causes."

"The second is that the public, whenever asked, tend to express an aversion to the tactic. A 2009 survey suggested that two-thirds of people would cross the street to avoid them."

These two assertions are not contradictory, but I wonder how many more lots of 600 000 people there are left to provide donations? What is the lifetime of a donor?
