Final answer:
Manicuring and pre-bussing are two different concepts. Manicuring is the process of grooming nails on the hands, while pre-bussing refers to clearing tables during a meal. Professional nail technicians usually need to complete a training program and pass a licensing exam to practice.
Step-by-step explanation:
Pre-bussing is the act of emptying and cleaning tables during a meal before the patrons have completed eating, whereas manicures are the act of grooming and adorning the nails on hands.
Depending on the jurisdiction, different training and certification requirements apply to professional nail technicians. To practice professionally, nail technicians must, however, pass a licensing exam and complete a state-approved nail technician curriculum in the majority of US states. Topics include nail anatomy, nail illnesses and disorders, appropriate sanitation and sterilization methods, and various nail augmentation and treatment approaches are usually covered in these seminars.
