The work is easy enough, as it doesn't take much to park a car. Every so often, you'll run into a disgruntled customer, who is peeved because you didn't do this in just right way, or something else.
The employees are mostly good people, except for a few oddballs. They're the kind that you wonder why they still have a job with this company.
The Supervisors are good people, but most of everyone's issues stem from the Manager. Personally, I find him/her to be very unprofessional, and not very flexible when it comes to requesting unpaid time off.
There have also been instances of the manager blatantly yelling/scolding employees in front of customers.
Verdict? If you need a job, then this is a job. But I wouldn't stay for longer than you really needed to.
