Your post shows that one can even get "not-so-good stuff" from LQS.
Do as others have suggested - send scans or photos along with a copy of the receipt -
The store owner/manager may not be aware of the problem - he/she can't fix it if he/she isn't told about it. If the shop purchased a stack of FQs, who would think to unfold every one to check them out?
It would be reasonable to me for the LQS offer to refund the money or replace the piece. The shop might want it returned - if so, I would ask to have the postage cost reimbursed, also.
