JoAnn employees are taught to cut to the exact amount, but some are sloppy. I have had fleece recut because the amount I ask for is the amount I need, not two inches less on one end. It does get you a dirty look, but I don't care. They are also taught to cut woven plaids on a line, not on the fold, but how many of today's employees recognize a woven plaid? My LQS owner cuts a little extra, but her husband and daughter are more exact. If I need 9", I buy 1/3 yard to allow for shrinkage as I am a prewasher now. I do find more shrinkage in width than length so I could probably get by with the 1/4 yard.
How do you get what you are paying for? Ask for it.
