Is this legal?

[Whatsit]

I work at a gas station/convenient store as a cashier/cook. As soon as I interviewed with my boss I liked her. Then she just never gave me a chance. Shes mean and unpleasant at all time to me. She will not schedule me to work on the days she does.

Long story short I was never trained on how to except coupons. And enter them correctly. Yesterday I was by myself and it was so busy. When i took the coupon I did it wrong and it paid for the whole purchase like 18.00. I let the assistant manager  know right away and he said your probably going to get fired. And snatched the reciept and stuff from my hand. And someone walked out with out finishing his cards pin and took his purchase and walked. 
 

in the morning i got a text saying you pay me 68.00. And if you dont pay your fired! I have no money at all.

Also even after I paid the money I just found out she wrote me up anyway.

Then you are very likely calling an old and disconnected number. You will need to find the current number.

As I said in your other thread, you need to start looking for another job. This one isn't going to last much longer.
