The charge that was dismissed doesn't count. But the pattern of arrests still suggests a problem of some sort. For a 3rd shoplifting charge I'd expect some jail time depending on the jurisdiction and 3 years of probation.
WHOA! YES, there certainly are minimum sentences for misdemeanors shoplifting charges. Here is the breakdown:
1st Offense - None
2nd Offense - $250 minimum fine
3rd Offense - Mandatory 30 days in jail
4th Offense or More - Felony.
