Leah, Leah, the more I read of your trials and tribulations, the more I think, (I will try to be kind), you need a attitude adjustment.
To give your friend, the advise not to tell her boss, about the loss of the license, provides volumes of information of how you think. It is true, your friend can throw the tickets away, that is a choice she makes knowingly, but what about the owner of the studio? He will also be charged and ticketed, without knowing the risks in advance. Not only will it effect his business and income but also put the other ladies working there further at risk as well without their knowledge. Please tell me you are not this type of women.
From what I have read now, I think I am more in Pleasing Brian's camp.
Please "Growup" and start to take responsibility for your actions. There is no free lunches in life, what you give out, you will get back, good or bad it is Karma working.I think if you change your attitude in a positive way, amazingly, your life will start to get better as well, both financially and personally.
Just my take on it. Sorry about that, I wish you well.
