I've worked in charities for years and have trained Street and door to door fundraisers.
I've never known of an agency over here telling fundraisers to approach women with prams. If I found out my fundraisers were doing that is bollock them. I've bollocked fundraisers for using street fundraising to pull women.
A few years ago UK research found that men signed up to women and vice versa. So if there are lots of male fundraisers Vs female the figures don't entirely surprise me.
Fundraisers aren't allowed to block your way and I don't think they should ever be putting their arm round your shoulder. There are strict rules set down by the fundraising regulator.
Bad fundraisers annoy the hell out of me. I once told one I didn't give a shit about baby seals. 😁
