I was thinking celebrities, but then people will misidentify them.
Each micro-service (in 2025?!?!) would have different pictures of a particular celebrity, for different errors.. so if the user says e.g. "I see Taylor Swift doing..." the support can say "Let me forward you to the S3 people!".
How much do you want to owe in license fees for their likeness?
Animals are way more cross culture compatible
