A lot of times service workers (waitstaff, people working at shops) will use sir/ma'am. This is also regional though. Where I live, it is not as common, both because of a culture of informality and because of respect for people who do not wish to be addressed as sir/ma'am. Some places show respect through implied hierarchy, others do not.
