Valet gave my Tesla key card to someone else

The valet gave my Tesla key card to somebody else. When the valet looked for my card they found some bent card that definitely wasn’t mine. They told me they accidentally gave my card to another Tesla driver.

Has anyone had any issues with valet and teslas and are there suggestions I should be aware of? I’m thinking of just owning an actual physical key fob with a unique key chain so other tesla owners know it’s not their key.
