These were about eighteen pence or twenty pence a-day before the tax, and they are not more now.

税前每天大约十八便士或二十便士， 现在不多了。

If you took a cafe serving a really great, expressive land full of coffees, bought ethically, unsustainable, and that cafe switched to something really cheap, really commoditized and very low quality, that cafe may save fifteen, maybe twenty pence of cost.

如果你选择一家咖啡馆，在一个非常棒的，富有表现力的地方，到处都是咖啡，合乎道德的，不可持续的购买，然后这家咖啡馆转向一些非常便宜的，非常商品化的，质量非常低的东西，这家咖啡馆可以节省15、甚至20便士的成本。
