Yes this has happened to me as well and I work inside a JoAnn's and watch this happen at the cutting counter frequently. However there is never anything lost on insisting that they remeasure the fabric because the cutting counter people at JoAnn's has to go through testing once a month anyhow and the ones that short cut are not sewers and should be pointed out and sent to work at the front end of the store or the back room. As far as the woman that someone was mentioning that was trying to purchase fabric for a whole cloth, if I was observing the process as a customer standing behind her I would have given her the courage to say no recut the fabric I cannot use this for my project and if they did not have enough because there was not enough on the bold insist that they find more at another of their locations and transfer it at no charge or not take the fabric and shop somewhere else. I can tell you that the fabric with the flaw had to be a big box otherwise the store owner never would have taken it. I find that most QS get the better quality fabric or the first instead of seconds on fabric runs. It will only be when we all stand up for what is right that things will change, whether we are the customer or standing behind them in line.
