If I can manage to have one of these on my garage shelf, I imagine an average A/C shop could have one.
A standard R/R/R unit has only one recovery tank. No shop will knowingly contaminate that tank with any of the R-12 substitutes on the market.
Yes, the substitutes 'work'. But innocently mention you've added them to your system, and the shop will likely decline to work on it.

I simply would not tell them.
I'd say i don't know what's in the system. Leave it to them to work it out and deal with it appropriately.
They have the means to deal with contaminated R-12, 99% of all systems that came in would be contaminated with something and so would not contain pure R-12.
Contamination is a well known problem and recyclers collect and purify used refrigerants for reuse.
Anyone that refuses to is acting purely for their own self interest and not because of some technical impossibility.
Anyone that expects to recover pure R-12 or any other pure refrigerant from a automotive A/C system is kidding themselves. By design Auto A/C systems are prone to contamination. I would expect to recover contaminated gas from all Auto A/C systems, not expect to recover pure refrigerant. They are kidding themselves.
I most certainly not encourage anyone to deliberately dump refrigerant of any type to atmosphere.
