The main judgement here seems to be: not everyone was there to get a refund, therefore, just entering the store is not an opt-in consent to biometric scans.
As a counter-example: Australian clubbing venues use facial recognition and id verification to identify banned individuals and detect fake documentation. This is required on condition of entry (therefore, opt-in), and this information is shared across all partner venues.
