Part-time waiters typically work an average of 20 to 30 hours per week. However, this can vary depending on the restaurant's needs, peak times, and individual schedules.
Many part-time positions may require waiters to work evenings, weekends, and holidays, aligning with busy dining hours. It's also common for part-time waiters to have fluctuating hours based on the season or specific events.
