Pros
If you've got the in with management and they like you, you have a promising career with a decent company. Sales will earn you big bucks and your name may become legendary. Hopefully your family members know some of management, or you manage to become friends with them. If so your future is secured. They treat their customers very well with the upmost of excellence at MOST locations. Their employees it really just depends on if your in with upper management or not. Again if your in expect to be treated like gold. You don't need to be a good employee or overly intelligent to be in, you just need to be well liked by upper management and those around you.
Cons
If you don't get the in with management then as long as your sales scores are good they will keep you around for a while. If you raise the alarm to anything that would be unethical, expect them to get rid of you. They will at times do things that you would question as ethical. Sales alone will not save you. You must have the "in". Also pay attention to the fact that a billionaire has recently had to bail out the company for massive accounting mistakes. Look up Carl Ichan. He deposited 1 Billion Dollars to keep the company afloat. Also note that they are typically 3 months behind on paying rent to outside companies as well as moving ahead with business plans. Since about fall of last year the company has become very shakey. I would recommend waiting to see if they come out of their slump with Carl's help.
