You mean Watto. ;)
It probably wasn't so bad to work for him, except for the whole being a slave who would explode if you try to run away angle.
As Watto was trying to get Anakin to essentially beat up some people who owed him money in Episode II, he had every right to blow him off. Plus he sold his mom off to some crazy moisture farmer!
In a way, Watto is the cause of Anakin's fall more than Palpatine.
And now I'm defending a prequel plot point. Just shoot me now! ;)
