I’ve already had quite a few do this and I’m only a few months in haha.
3 customers have said either their neighbour or family member/friend have asked for a business card, that they need a window cleaner etc, I pass them a card, haven’t heard from them.
Also when canvassing I’ve had a few say “oh I’ve needed a window cleaner for so long” I give them a quote, they agree to it, I say “I can book you in tomorrow or another day that suits?” I then get the reply “can I take a leaflet and run it past my other half it should be no problem, I’ll call you”
Needless to say I never hear from them.
