Hay, it's obvious that your tea-making skills are well below par so I would advise sticking to drinks that come pre-made in cans or bottles. (Saying that, I was in a right ropey corner shop the other day, and they had all these cans behind the counter. I was amazed when I started to read them and they were cans of vodka and coke, whiskey and coke, archers and lemonade etc. How crap must life have got when you nip to the shop for a paper, some lemon drops and a can of JD and Coke???)
