You can't use it during peak gas consumption. What's going on here?

The gas supply is insufficient. There is no need to use gas during the rush hour, because the gas supply is insufficient. The reason why everyone is using gas during the rush hour is that the gas source is insufficient. When everyone cooks almost, that is to say, some families turn off the gas stove before turning it on. This is completely normal. When cooking, you'd better stagger the peaks.
