Mugg n Bean focusing on going home than serving clients

I recently visited Mug n Bean with a party of 5 at 17:15. Our waiter, who was a black gentleman, informed us they closed at 6 pm, so we limited our order to coffee, despite wanting ****ins and cake. Before our waiter even arrived, a staff member began mopping around us, seemingly irritated that we had arrived "late". Her demeanor made us feel unwelcome. Meanwhile, the shop was still half full. Notably, a black woman arrived later, around 17:40, and was allowed to order coffee and scones without issue. It seemed inconsistent that we, a group of coloured individuals, were restricted due to the closing time while another customer was served closer to 6 pm. The staff's eagerness to start cleaning while customers were still present gave the impression they were more focused on finishing their tasks than serving us. If the shop closes at 6 pm, customers should be served until then. Consider adjusting your stated hours or ensuring staff prioritize customer service. As loyal customers, this experience may deter us from returning.
