Normally when I buy a sandwich for lunch I have Boots just ham, which is just ham NO BUTTER on plain bread, (unlike Tescos and Sainsburys "just" ham, which also has butter, which is therefore a lie and one that they should be prosecuted for). Boots Just Ham is also only £1, which means I don't normally get extras for the meal deal as it doesn't work out any cheaper. Yesterday, however, I plumped for a chicken and bacon wrap which was amazingly sans mayonnaise AND claimed it would be good for me, with nutrients. Since my diet in the past few days has mostly been cake, squirty cream directly into the mouth, cheese and ice lollies (hashtag no regrets), this seemed like a good idea. Thus, I was in the market for a free drink. I have heard people talk about coconut water, which sounded fairly rank as I only like coconut in curries. I had not previously, however, heard of birch water (which has never actually been mixed with any water, said the label), so I got some to try. Why do people drink it? It was like water (but not water) with a sort of synthetic taste to it, and it was slightly thicker than water and rather expensive and it didn't seem to have any vitamin claims attached to it. What is it for?
