I accidentally left my wallet here and someone found it and turned it in, however they helped themselves to the cash I had in there before they gave it to security. I was told tonight they can't do anything becAuse I lost it in the bathroom and there isnt any cameras in there so they can't figure out who it was. All they did was tell me I wasn't getting my money back and to have a better day. I guess i won't be visiting there anytime soon
