I understand what he's saying, if I couldn't get access to the back and I had priced a full
clean then I wouldn't clean the property full stop.
The mouthing or arguing would come when the cleaner called looking the full price for half a clean.
I certainly wouldn't pay it and wouldn't expect the customer to do so either.
I don't argue with my customers bud.
When I take them on I make them aware of how I work.
They agree, so they take me on.
If they try to pay half, I politely remind them of our agreement.
If they then try and argue, I take the payment they're offering and explain that I won't be back. Not aggy. Not to make anyone feel awkward or anything.
I have lost a few like this, over the years, only a few though.
It's not for everyone, but it works for me.
