A: I felt the car's transmission was lagging a bit. B: Really? I haven't felt anything. A: Have you had the transmission checked? B: I took it for a tune-up the other day. A: The mechanic didn't say anything? B: Nope. He told me that the car was in tip-top shape. A: Would you mind if I took it to my mechanic? Just want to be sure. B: Sure, go ahead. Would you like to take it right now? A: Let me check with my mechanic. B: If he is busy, then you can come back tomorrow. I am free. A: He said he is free tomorrow. I guess I can come back tomorrow. B: Great. Feel free to call me at any time.
