Replaced A/C Condenser but no oil in condenser or compressor to lubricate new O rings

I had a nearby auto shop evacuate my A/C system with the agreement of testing the vacuum and recharging it after I replaced the condenser as my condenser had a lot of missing fins in it, but no holes. It was missing at least five entire lines and another 5-10 half-lines of fins. I noticed, however, that when I was replacing the condenser there was no oil in the old condenser to lubricate the new O rings. I also had to disconnect the discharge line from the compressor to the condenser on the compressor side as the nut on the condenser side had stripped and would turn but would not move in either direction. I also left the suction line unplugged as the shop had left it unplugged so the pressure didn't build up, as the temperature of the area has been swinging into the 90's during the day. When I replaced the O ring on the compressor, I put my finger down into the compressor for some oil to lubricate the O ring but found just dust. I found the same when lubricating the condenser O rings, where the old condenser had no oil to lubricate the O rings.

When the shop is recharging the system, should I ask them to lubricate the new O rings? Or should I buy some oil myself, and do it?

Also why was there no oil in either the compressor or condenser?
