Vantaggi
If you are a high school/college student you have plenty of time in between lunch hour and when everyone goes home to study or read. There really is not much supervision, the job is easy to do does not entitle much no former experience is needed.
Svantaggi
There are a lot of customer problems so if you work for standard parking you much know how to separate business with personal feelings. The company does not value a students schedule it is not flexible it is set in stone and does not respect its part-time employees. There is also no way to advance within the company my former employee instead of giving me a management position in another location she gave it to her daughter. Instead of another employee with more years and experience.
