When the associate explained to me which clothes would be bought and which would not be purchased by the store. I was very agreeable. I told her I wanted to get a pair of jeans using the 20% off coupon on the bottom of my ticket. The associate told me she couldn’t give me a 20% discount because she had already given me the money for the clothes. The whole conversation lasted about 40 seconds. I told the associate “Seriously, you can’t ring up these pants using the 20% discount?” She said, “no.” 

I suggest you train your employees to ask if the costumer has a purchase using the 20% off coupon before completing the transaction.  These interactions come as across as absolutely no people skills and incompetence with computer skills. 

Thank you
