Roadster charging at Pebble Beach

No, sorry. When I was there, I charged using the 14-50 at the Tesla Store & also used the 70amp HPC in Salinas by Rabo Bank.

On the other hand, there is a lot less to go wrong with a NEMA 14-50 outlet compared to an old and uncared-for EVSE. The biggest risk might be that the breaker is turned off, or that it is inaccessible within the length of your cord due to vehicles or junk in the way.

Back in late July I charged at the Pebble Beach Market. The only issue was the plug was upside down and it put a strain on the cord.
