Hi, I need to get my car into the shop ASAP! It is backfiring all of the sudden.
Oh no! I can help with that. When did that start happening?
It started yesterday, and everytime I drive it since then it happens at least once, and this morning twice.
Ok. Where would you like to take the car?
I want to get it in at Intelligent Auto Solutions.
Ok, I can check their schedule.
I am off work until 5pm tonight. Want to get it in there today, by 3pm.
Ok, I am checking their schedule right now for an appointment this afternoon. Unfortunately there is no time available this afternoon.
Oh no! What about tomorrow morning around 10 am?
They are booked up tomorrow morning. I can schedule it early tomorrow afternoon. At 1pm.
Ok, I will have to rearrange my schedule, but I can make that work.
