Butano delivery

This is a very typical scene in every Spanish city, town and village. Most homes, cafés and restaurants don't have piped gas: so it is delivered by the Butano man.
When delivered to your home, he carries the bottle of gas, to your front door.....even if you live in a third or fourth floor apartment.
The price of gas is fixed by the government, as a way of controlling the cost of living. It is one of the very few items in everyday use, where the price can...and does.... fall. Last winter we were paying about 17€ for a bottle, and today this delivery man told me the cost, from his lorry, is 13€45cents.
So, as you might imagine, we intend to buy some bottles of gas in the next few days, because the price will almost certainly go up, as we approach winter!
