How long are you going to be at the gas station?
I don't know for sure. Not long if they're not busy. Maybe an hour.
Could you drop me off at the department store? I want to look at some shoes they advertised on sale.
Sure. I'll probably go over to the stamp market and talk to Tim while they're fixing the car.
Where should I meet you then?
I can pick you up in an hour and a half in front of the drugstore. Is that okay?
