The lady behind the counter of the Red River Cafe inside the Silver Reef Casino over charge me for 2 orders of Popcorn shrimp. When I did not take the change from the counter, she was upset and wants to know why. I mentioned to her NICELY that I was not given the right change.She quickly gave me back one dollar bill and said that it was struck inside the till. I got the shrimp after waiting for 5 minutes. After eating the extremely salty shrimps, me and my 3 friends were drinking tons of water for the rest of the day. We did not eat for most of the day except for some bread and all the water we had to consume because of the shrimps. I had to get up many times during the night to drink water. My throat is sore this morning due to the excess MSG and salt in the shrimp. Could not sleep, and I woke up this morning at 4:30am with a sore throat.
