Female owner greeted our dark-skinned teenagers with distaste. She growled at them not to scrape the chairs on the tiles which proved very difficult. We moved outside to avoid this scenario. A group of older white people came in next and scraped their chairs as anyone does when pulling them out but the owner did not say anything to them. She continued to scowl at our group the rest of the time we spent here. The male owner however, was lovely, friendly and polite.
