There is a lot of holier-than-thou posts on here today !
In the last 24 hours, I have bought a cup of tea while waiting 2 hours at my Ford Dealership, and this afternoon, I bought another cup, while waiting to see my brother at the Hospital.
In neither occasion, did I fell remotely overly profligate with my money. In neither place was it possible to have the drinks in "proper" cups.
The answer to this problem is for the recycling industry to get its act together. It can't be rocket science to be able to recycle a simple thing like a hot drink container !
