Comment: A company that makes 5.2 billion EUR selling off its most profitable business unit can surely dig deep in its pockets to find the cash to offer its distinguished guests a decent cup of coffee. No. It'll promote its plastics (disposable cups), and minimise its environmental impact by not heating the water.

This must be the tip of the cost-cutting iceberg.
