Cool tip 7: Gas stations in Brazil
Gas stations in Brazil are not self-service. In order to fill up your tank you have to wait for a “frentista” (attendant) to come and fill it up for you. All you need to do is tell him or her how much money worth of gas or ethanol you want (many cars in Brazil are now “flex”, that is, they run on both ethanol and gas) and pay him or her at the end. It’s not the custom to tip “frentistas” for this service, however if you ask him to check the tires or the oil, then a tip is certainly expected!
Gas (or any other fuel such as ethanol or diesel) in Brazil is measured and sold by the liter.
