Pros
As a party hostess, you get tips and can meet some really great kids and parents. Management is very approachable, you can ask them anything and they will help you. Great experience in customer service. Very easy to get a job. Some of your co workers are really great people.
Cons
The customers are often time extremely rude, expecting this experience to be perfect. Tips are infrequent after the first month. Politics dominate (at least our store.) The people who don't work hard get the hours, and those who do work hard get their hours cut. Personally, I've had my hours cut to 6 hours roughly each week, which is why I'm finding somewhere new. At peak hours, it is possible to be trapped at the last place you need to be for your job for an hour. If you are in high school, as most are, and the ambitious/intellectual type, I would not recommend this job. A lot of your coworkers will be focused on drinking and partying, which can be uncomfortable if you don't drink.
