An Auckland cafe owner says its star rating declined after a customer criticised the business online for displaying a Taiwanese flag, RNZ reports. Owner of Cosmo Coffee Jason Park said his eatery was left a one-star review due to the appearance of the Taiwanese flag beside an item on the menu. After getting the review removed from Google, the cafe has since received eight more one-star reviews. They all come from new accounts and do not respond to requests to elaborate on any issues.
