If there is a power outage during business hours, those without generators can only suspend business. Usually, it's not just one store that loses power, but the whole area, and all restaurants have to rest (unless they bring their own generators); Although the gas-fired stove can continue to operate, its necessary electric smoke exhaust system has stopped working. It is very dangerous to use a gas stove that does not smoke. A lot of oil smoke can't be discharged outdoors, so you can only choose to rest. Moreover, some gas stoves can only work when combined with electricity (such as blowers), so they can't be used when power is cut off; In addition, air conditioning, lighting and other electrical equipment have stopped, which is not suitable for operation.
