Just don’t bring valuables? What would you need other than a phone and cash? After handing over the main chunk of cash, then it’s just your phone and tips, and nobody’s gonna touch your phone especially these days with Find My, etc. If you’re worried about theft of your socks, pants, underwear, shirt… well I dunno how to help ya cuz I really can’t imagine anyone stealing your socks, etc.
In all my years I don’t think I’ve ever had any provider come close to touching my phone or extra cash. The only exception is when you start dating providers and I had a bad experience in one particular relationship and it took me a while to realize she had gone through my wallet when she was staying over and charging shit on my credit cards. And I also collect rare currencies and I had a bunch of it stolen too.
Stick with reputable providers and agencies… use reviews here and you’ll be totally fine.
