Cat droppings coffee costs £50 a cup！！！！

There are so many hot drinks around us ,tea, coffe, hot chocolate ,also juice ...coffe is one of the most popular drinks in our lives. People do like coffe's taste what is a bit bitter but still tasty,that's perfect ! So do I.
But normaly do you know how much for one cup of coffe?I suppose might be 1 or 2pounds.Even in the "Starbucks"might be 10 or 20 pounds although I never been to there, just I suppose!The price is ok for me but a little bit expensive,because the exchange rate~ So if I spend 10-20 pounds on a cup of coffe I could accept it. But today I know a kinds of coffe which is the price 50-100 pounds...!! Oh,god! I have no idea about it bucases I think it's so expensive ...but let's see why it's can be expensive like that ?The reason of the problem is : "the drink is a blend of Jamaican Blue Mountain and the rare Kopi Luwak bean, which sells for £324 a kilo." That's why it could become "the world's most expensive coffee".
And also in my opinion that not a good business idea.why I think like that,because even though it has very good material good quality and good tastebut because the price it wouldn't accept by most people ,so it wouldn't have so many customers,even they have some just some rich people or someone who likes enjory life.So taht's might mean this coffe won't have a widely market... that's why it won't earn lots of money.
We can see this taype of coffe cost a lot . So the manager couldn't make so much porfit oppsite might cost more than income...because just look at the variable cost already quite considerable...and I think because the coffe is very diengnity so it must need a good environment to create a coffe shop so the fixed cost wouldn't low.So the business like that total cost much more than income may be won't have successful!
But everything is not absolute. This just my opinion.But I also know a way about if you just sell ration coffe... may be you will make porfit!
In fact for myself I can't accept just a cup of coffe costs me 50 even 100 pounds...
