It's not critical to remove all the mineral oil if you add more oil that is compatible with it, 134a, and your system. In a perfect world you would use compressed air or some other method to blow as much old oil out of the system as you could, followed by solvent, followed by evacuation. After evac, you can then add the refrigerant oil. I normally add mine with one of those little piston tools through the low side shrader valve so I don't have to break the system open.

Your jobber either lied to you or just doesn't know what he or she is doing. The receiver/drier should be sealed from ambient air. I'd make them take it back and put another one on the car. You can use that opportunity to change the expansion valve at the same time.
