Long John Silver's

I went to Store # 31538 on 9-28-15 at lunch time at Drive thru. told cashier I had a coupon for $4.99 for 2 piece combo, included 2 sides and 2 hushpuppies. once at window I asked if they got both sides, she said it only offers 1 side, I said coupon said 2 sides. she looks and shows manager, he said because I did not state what coupon I had he will not fix it and put in both sides. I said yes I told you and you have the coupon. she said sorry the manager will not do it. so I go to Long John Silver's website and submit a complaint.. It goes to the MANAGER! what good will that do when he is clearly the problem! I found this, we will see if this is wasting my time or not. probably so. And LJS wonders why their business is failing.
