Save yourself the money and drop the houses and only clean houses with 100% access. You'll learn to sift the dross out of your round sooner or later, so why burden yourslef with more kit?
Nuts, if you have good reliable customers your shooting yourself in the foot by just dumping them, just because it takes 2 more minutes, and you need a backpack.
Rosy, in a lot of posts I see the same negative 'dump all customers if you even have one tiny hint of discomfort', not the way to run your business professionally. You should strive to do the best service possible, sometimes that means going a little out of your way for good customer service.
So what you need to get your backpack out of the van.
Wrong wrong wrong.
You are so wrong.
I'm not being negative for the sake of it, it's (for ME) about sifting and sorting the wheat from the chaff. When youre new, like it sounds you are, you take on all kinds of junk, a few years down the line you realise what's been happening (like I do) and just insticntively know you have to cut the crap out from the round. You have to aim for perfection, yes, but to me that means getting the customers perfect (no locked gates, cash payment etc blah etc. etc.), it doesn't to me mean charging more and putting up with locked gates, dog poo over hoses, stroppy people, rose bushes and all the other complaints.
I'm being serious here. I'd rather have a nice working life than be a slave to these people.
