Can I make a phone call at the gas station?

You can't make a phone call when you refuel the car. There is a danger of explosion.

When a gas station injects gasoline into the fuel tank of a car or motorcycle through an oil gun, the oil and gas in the original empty fuel tank will drift outward, and the newly injected gasoline will also volatilize into the air, so that the oil and gas density around the refueling vehicle will suddenly increase. Because computer control is widely used in filling stations, computer equipment will sense high-intensity mobile phone signals, and the instantaneous electronic friction between them may ignite fuel vapor and cause an explosion.

Therefore, for the safety of you and others, please don't use electronic communication equipment such as mobile phones at gas stations.
