Rather depends if they're happy to extend the cleaning service to do your bins as well, doesn't it? If not, I think I'd be developing a regular shellfish habit once the weather warms up. Now, what to do with all those shells and trimmings... 
We have a dog so I don't particularly care if someone else puts something smelly in our bins (in fact it's preferable to them dropping litter or leaving a poo bag hanging in a tree
), but that's our choice, and it's very different to maybe slipping a few extra bits of recycling in on collection morning.
