The law works in the emergency service - PAY was called! But the emergency room should be arranged for free! (If you give me a check, they won't give you one. They called their superiors, but it turned out that emergency work is free for the public.)
I would advise to supply all consumers with gas meters, and to change gas columns every 15 years, if anyone has any.Naturally, as it should be, it should all be free.
