if you have a dollar what will you do

i think the value of 1 Dollar here is pretty much same as in India

In the UK $1 is worth about 60p. That would buy me, perhaps, half a loaf of bread or less, maybe half a litre of milk or something like 300g of butter. 60p would also buy two oranges or two lemons or two cans of the cheapest tomatoes. I could drive my car for about four or five miles for that amount and maybe make a five minute call from my landline to a mobile number (though there are many different phone plans which give one 'free' minutes, so that isn't a good example, perhaps).
