Way too many variations here that wouldn't positively reflect the HomePod. That would depend on where the HomePod is positioned in the store, But if you have a store that's hectic with a high volume of customers talking, phones ringing,etc, there's no way you can accurately judge how the HomePod sounds based on that environment alone. You have to factor in those who actually have a HomePod in your house, you will be able to hear more nuanced tones and how the HomePod would ultimately sound depending how they have it stationed and what kind of room, how high the ceilings are, etc. That's all relative to the experience.
