In Malta and what we’ve seen of Spain, there are not underground gas lines to homes and businesses. Instead, the delivery man has scheduled routes. A good job for the physically inclined in carrying full tanks to doorsteps, and taking away the empties.
If a home has gas, it’s typically used for stove, hot water and maybe heat in the northern areas.
Always being watched. Bluest skies.
Making the corner in Malta, the driver made his presence known early one morning (!) by tooting his horn. – Laura
