Oh, 100% - I used to do the same too 😂 Those sort of drops are awful, especially if you've got a massive shop or crates of water etc so any help is massively appreciated. They'll have likely left notes on their tablet too - you could leave notes for any future drivers to a specific address to warn of a dog, or dodgy steps etc.

Ocado, at least when I worked there worked on the basis of "you can teach polite people to drive a van, but you can't teach mean people good customer service" when recruiting and it generally worked quite well - they'd always encourage you to go the extra mile as ultimately that's what keeps customers coming back and it's not like they had a bag counter at the depot, so you had free will to do what you pleased really.

I delivered to elderly people quite a lot, both in supported flats and their own houses - I'd unpack their fridge and frozen and put it away for them, and leave any dry goods on the counter top so they didn't have to bend down and so on. You'd try to have a little chat if your route timing allowed too as it's often their only chat that day aside from their carers, which is quite sad really.
