What kind of gas does this car take ?   I don't know . It's a rental .   I will give you premium unleaded . Alright ?   Sure , why not ?   That is the pump you are in front of .   Is it expensive ?   It is the most expensive .   Well , I don't want it then . Can I move to another pump ?   Yes , I can give you regular unleaded . But you have to back up the car a little .   Give me regular unleaded then . I will back up.Can you wash my windows for me ?   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 .
