Unsafe place to hold money! Guys...please be caref...

Unsafe place to hold money! Guys...please be careful with your valuables here as you cannot trust the security folks at the entrance of the Tower of London. This person took our cash , we lost 200 pounds !!! it was placed in a safe and secure location pocket in our back pack and the security guy put his hands inside our bag into all the compartments and flicked our cash just like that! when we went back , he wasn't there at the entrance and we lost 200 pounds!! who would think this place was so unsafe for tourists especially by the security folks at the entrance!! what a sad day for us :(
