I've gotten called 3 times, the first time I was dismissed because it was an abuse case and I had been an abused child. The second got cancelled and the last one I'd prepaid for classes for that time frame so they let me out.
It's just crazy how they do things here. In Norfolk, you have to call the number they give you once a week for a month to see if your number comes up, you can only be summed to come once during that month. You get great doughnuts while you wait, I get paid from my work as well as the city. One of the other cities, you have to call each night and can be told to showup as many times as they want to come in during that month. So glad I don't live in that city. They used chose people by their voters registration but some dont register to vote to avoid that, now they call by car registration. You can't be called more than once in 3 yrs and now that they have a bigger pool, it takes alot longer for them to get around to you.
