Sometimes people send the wrong signals when using their phones (either as phones or as cameras) in stores. If you prefer to shop locally and have intentions of supporting the business, please just put your phone away for the brief time that you are there. It sends a signal that you do like to base your decisions on feel and color and scale. Notice how helpful a clerk can be when you are gazing adoringly at a fabric with no electronic device in hand! Very helpful! I am a quiet shopper with a very good memory. I won't take a picture of a piece of fabric or a bolt end in the store, but I may scribble a note to myself on a scrap of paper after I have left the store.
