I went into Joann's to buy yarn. I found a coupon on my phone for $5.00 off on a $35.00 purchase. The coupon that showed on the phone when I got to the register was for $5 off on a $50. purchase. I tried to tell the sales clerk there was another coupon but she was laughing at me & said no there isn't you will have to come back & buy more as my purchase was $45.00. When she gave me my receipt she handed me a coupon from the register & still laughing said here's another coupon for you. What a jerk !!!! I didn't pursue the matter as there was a line & I was embarrassed by this obnoxious cashier. I will think twice before I shop at that Joann's again. I would rather shop on line & then I won't have to put up with this person again.
