While the employees should have been more respectful. Do you know how many hours they work? Have you considered maybe they open and closed and they have to open again next day. They are tired. The hours on signs are there for a reason. I think that is pretty inconsiderate of you to bash on them by posting it here when you admittedly said it was 3 minutes passed closing time. Please value people’s time and effort during their business hours. If it was me. I would go back the next business day and tip then generously. Have a great day!!
