what happened today in my spoken english class

It was another profitable/fruitful spoken English class. We talked about renting a car, making a reservation at a hotel, solving some problems. We took advantage of this class to practice/practise the usage of/the use of/using phrasal verbs and idioms. ('the usage' is more or less theoretical, so really it should be 'practise using') We talked about making a reservations at a hotel/reservations at hotels, making the checking in, solving some problems such as like when someone is inside an elevator and it stops working. In this situation people have to ask for help (you're forgetting about the people stuck inside!) to take the baggage to the room.  Once inside the room, this people has they need to order for extra towels, sheets and pillow cases. We talked about some parts of the aspects of a car, like flat tire, wheel, windshield, windshield wiper, gas pedal, break brake pedal, traffic lights. She taught me the usage ot the phrasal verbs RUN OUT OF GAS and RUN ON FUMES, (??? that is perhaps an American idiom) (we say 'run on the smell of an oily rag') when someone is almost without gas in his car (I think the American usage is more metaphorical, and refers to people with low energy). We talked about how to get the a driving license/licence in the USA. I learned that someone can get a driving permit to drive a car until this person gets the passes the driving test licence. We talked about the bad idea to downside of returning back the a rental car to the renting car company without gas, once because those companies charge a very expensive high price for the gas they have to supply use to refill the tank. So, it´s better to turn back return the car to the car rental car companyies with at least the same level of gas as when you picked up the car up.
