Yeah. Travel purses may be very useful sometimes. I remember I was in Germany 3 years ago, and I was traveling for a few days with little to no sleep. I had a backpack and a traveling purse. Due to tiredness before getting on one of the trains, I left my backpack on a chair on the platform. Luckily I had a traveling purse to keep my money, documents, and other important stuff that was on me. I approached one of the representatives from https://www.dbauskunft.com/de/, and they were super helpful and got me my backpack in no time.
