a cover up

had supper at their restaurant spent about 3k, upon tipping the waiter accidentally dropped 2k. when we back requesting for them to show us the footage as we were also the last people to leave the restaurant the 1st manager said they can see us but not sure what happened to the money, next day a different manager claimed that the cameras were not working. the owner claims the angle of the camera does makes it difficult for them to see us. 3 different stories only leads to us thinking was ****** by someone from there.
