I would definitely call the store. If nothing else to let them know that their clerks are not paying enought attention when they are cutting. My all-time favorite fabric store - Yoder's in Shipsewana - always flips over all of the fabric before they cut it. {That didn't make sense} When they are getting ready to cut your fabric, they will unroll the bolt enough to have what you are wanting, then visually check both sides before cutting. My husband says that this is 'just because the women are Amish' but I say it is because they are quilters and sewers themself. I try to always look over my fabrics before I leave the store. If I haven't been able to really look at it while it is being cut, I will go the back where there is an extra table and unfold it, examine it and refold it. I ALWAYS fold better than most of the store employees do.
But I would call the store. If I was the owner I would want to know. Customer service is - or should be - their number one priority.
