Why would the OP feel silly??
Until maybe 6 months ago i would have agreed with her indeed like her cinema my cinema had a waste bin right on the way out of the screens. And an advert reminding people to take their rubbish woth them. I was kind of suprised last time i went to see all the notices saying please leave your rubbish in your seats we'll sort it and recycle it.
So actally the OP was correct, she didnt realise tje cinemas prefeance had changed.
I bet you feel silly now lol bigredlondonbus and as for never seeing people clear up after themselves thats rude And says far more about you than it does OP or the rest of us!
Why not just have a recycling bin?
I think roweena because a lot of people see a recycling bin as the same as a general waste bin and stick.even non recyclevles in. Or they'll put stuff that is recyclable in the general waste bin just cos either they don't care or they don't know its recyclabe because it might not be recyclable in domestic collections. But cinemas will use commecial collectors who may have access to more kinds of recycling.
For instance in my previous job we were looking at our waste and recycling collection contracts and one offered the oppunity to recycle those terapak cartons (you know the ones with the foil lining) the one that we were using did not, where as the one that we were using said some different types of plastic bottles were recycleable that the other company did not recycle.
Also different companies want things sorted in different ways. All paper and card might go in one bag or their might be a paper and card bag and a soiled paper and card bag (ie card thats been used to serve food) or plastic bottles might go in one bag but their lids go in another.
Once its all gone in to the same bin you might as well just put it in general waste because you cant sort through it.
