Why do customers talk about the price every time they customize clothes and make samples, and then change their minds when the goods are big?
If it's really not the fabric, it's that they want to reduce the price, because the big goods have already been delivered, and if you don't reduce the price, they will refuse to accept the fabric on the grounds that it is unruly, causing a backlog of inventory for the manufacturers. To put it mildly, they just push their luck.
