Vantaggi
The only pro I can think of is that Meijer is a good place to be trained for cake decorating. They will hire you with no experience and train you. It's a good place to get an idea of basic decorating so you can eventually move on to something better rather than paying for classes or schooling. They are also very strict about making sure you get all of your breaks and lunches, you can be written up for not taking enough breaks.
Svantaggi
The cons are that there isn't very much room for creativity. Meijer is very strict about the cakes that can be displayed or made for special orders. There is never enough hours given to the decorators to be able to keep display cases full at all times and I feel that management purposely short staffs the employees to get them to work faster. The store directors don't really seem to care why the cake cases are empty, and they don't take the time to figure out what the problems really are they just tell you to fill them up. It's a never ending problem that I grew tired of very quickly.
