My babysitter gets mad when my husband keeps my daughter

Am I wrong in being mad I told her today that my husband was able to be off work tom and so he will be keeping her and she freaked sayin she gonna look for a job cause she can't afford losing days. She always gets mad when family wants to keep her. But then I find out that she went out tonight and got a tattoo!!! Am I wrong in thinking that if u can't afford to lose a day which amounts to like 20$ u can't afford a tattoo??!! And that a babysitter is ment to be when you are needed not when u want her. We never agreed on a certain amount of hours or money each week.

So am I wrong?
