In my experience, TS auditors tend to be pretty rigid from day one but a recent Aerospace audit (AS9100, Rev C transition) was, IMO, a good case of "moving the goalposts" unnecessarily. The Auditor even "apologised" for being overly harsh on us on the 3rd revisit but congratulated us on a solid, well-implemented QMS.
Sadly, the situation is, in many cases, just a case of doing your best and, in the case of TS, make sure that you can justify anything that looks as though it doesn't quite meet the letter of the standard against the intent of the clause. It's worked for me but that may just have been good luck!
