Many retail stores are open on Christmas Day to serve last-minute shoppers and provide essential services. Some examples include convenience stores, gas stations, grocery stores, drug stores, and coffee shops. These stores often offer extended hours to accommodate the increased demand for last-minute shopping and provide a convenient alternative for those who don't have access to other stores. However, it's important to note that some stores may have limited hours or be closed entirely on Christmas Day, so it's always best to check with the specific store in advance to ensure they are open.
