The classic in my recycling bin (which had been put out at the end of my drive ready) on recycling day
an expensive piece of electrical equipment was just shoved under a bush behind my gate - and they didn't even say it had been delivered so I didn't look for it for 2 days (and yes, it had been raining, so perhaps a blessing it was under a bush)
Literally thrown into my front garden in pouring rain.
'Under your tractor' (I don't have a tractor)
And obviously to various neighbours (despite me being the only one with my postcode, and giving clear instructions about what my house looks like in the first two lines of the address, me having a nice, safe porch to put the parcels in, and these neighbours being 100s of yards away). I did enjoy the customer service once asking if I was sure that the picture wasn't of my house though. I liked the confidence.
