Maybe what I read from this: LC could offer an extra option where there is a video of the frame with all the checks one would like for quality control before shipping. How much would that cost? In this case everyone would feel at ease and there should be less surprise.
We could probably come up with a standard procedure and call it the Chinertown Protocol.
You'd need a robust ERP to make this viable, so that the right video is uploaded in the right place and made available to the right client. It would be nice, but feels unnecessary. Also, it would slow things down, because you'd have customers having to effectively sign off on the frame, that can easily add 1 week on average, because now between paint and shipping, you have an extra stage, extra storage, and so on.
Alternatively, and more simply, it's called basic QC, where the factory isnt supposed to ship unrideable garbage. Where i come from, people take pride in the stuff they make. Right or wrong, If i receive shit in a box, i feel personally insulted.
