"under-manned"? Then it is obvious. Hire women. But seriously, the under-staffed excuse is too easy. It is interesting to see how things look different when the focus is on BAD processes that create WASTE. Tesla service is a beehive of people trying to manage bad processes. Firefighters. From searching shelves for parts (that's where they finally found mine) to the frustration THEY have with "the app". The list is long and talking to service center employees causes the list to get longer.
