Petrol pumps, also known as gas stations, are facilities where vehicles can refuel with petrol or diesel. They typically have multiple fuel dispensers, allowing several vehicles to fill up simultaneously. Most petrol pumps also offer additional services, such as convenience stores, car washes, and air for tires. The fuel dispensed at petrol pumps is stored in underground tanks and is delivered through hoses and nozzles. Customers pay for their fuel either at the pump using credit or debit cards or inside the store. Safety measures are in place to prevent spills and ensure proper handling of flammable liquids.
