Our little road has a close leading off it. Our house is on the junction and 'les ramasseurs' sometimes leave bins in any old spot. We keep our bins very clean, and we don't want someone's stinky bin returned to our house. Having our house number and street clearly printed means we always get our own bin back.

We always give the men a Christmas Box (tip) and some cans of beer, and in the summer ice-cold cans of Coke/Fanta if there's a heatwave. Also if I've been baking they get a few treats as well (buns, cakes, mince pies etc).
They're very helpful if we have something a bit large. They once cheerfully took an old ironing board away for us. Really nice blokes.
