At our local thrift shop the "good" stuff never gets on the shelves. Acc to reliable sources the workers sort through and take what they want and then stock the rest. One woman was taking lots and was selling it at her own private garage sale. She was caught. My daughter gets lots of her kids clothes there because they are growing so fast. I have found some really nice stuff for quilting and wearing. My fav was a wool jacket from Nordstrom (still had the tag on it) for $20. Original price was almost $250. I haven't noticed critical people, just indifference.
