I do all my collecting on Sundays (Waits for abuse
) and can honestly say, haven't had a single neggy response so far. About 50% of our domestic custies work so it's the best time to catch them at home.
Don't second geuss your custies mate. Same with working in wet weather, some will, some wont, if you see what I mean.
Anyway, what's the worst that can happen?
I only collect from one customer and I only do that every 6 months

when I am due to clean their windows I either text or telephone, and if they are not going to be in they either put the payment somewhere safe or they post or bac it into my bank account.
Back to the canvassing issue, I use to be a door to door canvasser and I found that saturdays - sundays and bank holidays where the best days to door knock.
I think the reason is, in the week they are at work all day and get stressed, then they come home and all they want to do is relaxed.
This is then broken by you ringing the door bell and even though they are ok when they open the door, their mind is switched off to what you are saying, so they automatically say "no thank you".
On their days of rest, they are not stressed out and their mind is open to what you are saying and you have a beter response.
Now before the "sunday is precious brigard" come out crying that you will go to hell

remember that most families like to go to sunday markets and car boots on their rest days, they enjoy it.
