No one wants to be in a hairy situation–pardon the pun–while traveling where they’re torn between carrying too much cash with them or alternatively leaving too much cash in a place someone else can access. Sure, you have a locked room, but there are a lot of staff who can enter your room as well.
There are some sneaky places to hide cash that no one would think of, one being a hairbrush. That is actually genius, since anyone who tries to take something of value from a hotel guest would never think of snatching a hairbrush. With this nifty hiding spot, you can travel the town without worrying about the extra cash lying around your hotel room.
