Hmmm.
I've just picked up this otherwise dormant topic during my work in migrating various existing posts from our 'the wider picture' board to one of the new boards, so please accept my apologies for the delay in my response / resurrecting an old topic.
Suppose you don't get dirty clientele at your partnership that you want to clean yourself after visiting!
You would be surprised. I have two examples of customers who, while obviously able to order their shopping online, were apparently unable to look after themselves in their own homes. In one case, I referred the matter to social services, as I was so concerned. That was the one where I actually used the hand sanitizers in the van when I had completed the delivery. It was that bad.
Since my previous post I now do the same role as you, but in an orange branded van. I'm glad I haven't come across anything like this.
We've a fair few customers who have their order done by family up country, and we can be the only people they see from week to week. I take longer and have a good chat with those.
