Have you seen all the people who have gone into a coffee shop for a takeaway coffee and then carry it a way as if their life depended upon it. However, at the prices they charge, this is not much further from the truth.
Also, have you tasted some of these coffees, well if you have not it is an experience, but one you could do without. Last year I was going on holiday to Inverness from Sheffield and while driving up there made a number of stops for refreshment breaks and tired a few coffees from Costa Coffee. In the main, all I can say about them, is that they were hot and did quensh my thirst, but then so would have a drink of water, but it would have been cold.
