This review concerns the McDonald's in Friendswood, Tx at the 518/528 intersection. I paid attendant for my order with a twenty and while I was putting my wallet away, she placed the change on the counter and disappeared. What I noticed was that she had given me incorrect change. I called her several times and finally she came from behind a wall. I said the change was incorrect because I had paid with a twenty. She said, "No you paid with a ten." I said, "I had thirty dollars in my wallet, one ten and one twenty. I decided to pay with the twenty because I was going to need small change for my grandson." Finally, the manager came and said the cash box had been balanced a few minutes ago and that there were no twenties in the box. I said, " I don't know what she (the attendant) did with the twenty, but I gave her a twenty. The manager took the cash box away to rebalance and said it balanced correctly and that I had paid with a ten and not a twenty. I insisted that I had paid with a twenty. Finally, a video was shown and I saw myself paying for my order. The manager said, "Do you see yourself paying with a ten." I said, "No I don't, how can you tell if it's a ten or a twenty when the video is completely out of focus." She said, "I can tell because the ten and the twenty are different colors. I said that they are the same color. I asked her for the name and phone number of her higher up and she refused. I asked her to take my name/number and to call me if at the end of the day the balance was over ten dollars and she refused. Finally, I went and asked a policeman for help. He came and the manager finally agreed to take my info and said she would call me. Two weeks have passed and no call. Terrible, terrible, terrible! Is there any justice when a company is so powerful that it can do whatever it wants to customers? Ten dollars owed me is no big deal, it's the principle that matters.
