Always photo copy your tickets
I haven't done a lotto pool at work in a long time, but when we did, I always stressed that tickets bought should be photocopied and then email to each of the parties involved.
Based on this article it sound suspicious that this lady purchased all the tickets at once, then claims that the ticket that one was not part of the work pool but personal.
It appears some very angry people are not on speaking terms now.
