I had a new scuff on my door (just above the PPF, annoyingly) after I'd picked it up from the same SC, that had been touched up (badly) as well. Only found out after I washed the car and noticed the water beading off it differently - as the car had previously been ceramic coated.
It was small - maybe 1" - but bearing in mind I knew every inch of the car and it had only done 700 miles, it stood out to me.
Phoned the SC but didn't really get anywhere, as I had no proof, and it had been a couple of weeks since I'd picked the car up. Sentry etc gets disabled as soon as the car is put into service mode.
Basically, either the car picked up this scuff while it was at the SC - and they touched it up without telling me it had happened, or when I was at the supermarket Mrs Miggins scuffed it and whipped out her Tesla touch up pen that she carries with her at all times, that happened to match my car colour exactly.
Hmm..
