One of my lqs has monthly sales which often include all fabrics with a certain colourway and or motif, such as any fabric with red or hearts on sale the month of February. I have found that if I am uncertain if a fabric is on sale, that they err on my side and give me the discount.
The other shops, put the sale fabric on a sale rack, so you know which ones are included in the sale.
It sounds like the owner was having a bad day, perhaps triggered by a personal matter. It is unfortunate that you bore the brunt of it, but as you said in your later posts, your past experiences have been pleasant. It would be nice if we can shut off our emotions when at work, but sometimes it is all we can do to keep it together.
One of my lqs owners has been battling cancer for several years. She is open about it, which allows her to receive compassion and good wishes from her customers as well as lets us understand when she is having a bad day.
