Question about mechanic …

we are towing my son’s car to the Kia place for repairs. They know that it’s coming by tonight after hours for tomorrow morning’s early appointment.

I just want to know how does the mechanic get the car from the parking lot into their garage because it’s not drivable. It has to be towed. do they have like a mini tow or how does it work? I kind of need to visualize how this is going to go
