ATTENDANT: Can I help you, sir? SAM: Yes, I've been sitting here for a few minutes.I'm waiting for someone to put gas in my car. ATTENDANT: I'm sorry, sir. But this is the self-service pump. SAM: Self-service? ATTENDANT: Yes. You must fill up the car yourself. SAM: Are you serious? ATTENDANT: Yes. Are you traveling here? SAM: Yes, I'm from Taiwan. I never heard of a gas station where you fill up your own car. ATTENDANT: In America, most gas stations are like this. SAM: Do I really have to do it? I don't know how. ATTENDANT: Well, since this is your first time, I will do it for you.But next time, if you want a full-service gas station, you should look at the sign. SAM: What sign? ATTENDANT: Under the sign for the gas station,there will be a smaller sign that says "Self-Serve" or "Full-Service."And some gas stations have both.But if they have both, some pumps will be self-serve and some will be full-serve.You have to look at the signs. SAM: I see. ATTENDANT: What kind of gas does this car take? SAM: I don't know. It's a rental. ATTENDANT: I will give you premium unleaded. Alright? SAM: Sure, why not? ATTENDANT: That is the pump you are in front of. SAM: Is it expensive? ATTENDANT: It is the most expensive. SAM: Well, I don't want it then. Can I move to another pump? ATTENDANT: Yes, I can give you regular unleaded. But you have to back up the car a little. SAM: Give me regular unleaded then. I will back up.Can you wash my windows for me? ATTENDANT: I'm sorry, sir. This is not a full service gas station.I will help you fill the gas, but we don't wash windows here. SAM: Really? Well, I guess I have to get used to it.
