I think gas stations can be one of the more stressfull types of retail stores to work at because there is a risk of being injured or killed in a gas explosion and fire when you work near many gas pumps, sell propane, other flammable liquids and gases and there is a gas truck which occasionally fills up the gas tank for the gas pumps. The workers at the gas station need to use a fire extinguisher to put out a fire, and possibly rescue someone who is on fire or trapped inside a burning car. I also hear a lot of news stories of gas stations being robbed by a robber with a weapon like a knife or gun, or the gas gets stolen where robbers use a barrel to steal gas, and the gas may explode while being filled into a barrel. Gas stations also seem to attract homeless people who use the gas station to beg for money, and do other stuff, so the cashier sometimes need to ask them to leave the station. Plus, the cashier sometimes need to sell food, give directions, clean the toilet and floors, stock the shelves with food, and other stuff, and also do simple car repair like replacing a car battery, or pouring in windshield washer liquid into a car since most gas stations also has a store and sells food like donuts, and car products. I guest, it can sometimes be a lonely job if the gas station just hires 1 cashier to manage the whole station.
