I’ve easily been to around 50 of these barrel stations in northern Thailand, and not a single one of them had any diesel fuel.
Valid point, but it’s not uncommon for vending machines to be out of order for several days at a time.
As a motorcycle rider, my main source of fuel in remote areas is usually barreled fuel shops because vending machines are often unreliable. While I don’t have any problems using ‘amenity=fuel’ for all fuel dispensing categories, I do need some additional tags to distinguish between them. What would you recommend?
