Quoted from karl:
One of the things that led to trouble between DP and Phil was that Barry was taking money out of DP because he was working full time on TBL for awhile, while the others had jobs.
I do not remember how much it was and to be frank, I do not see a problem with this. I bet he was working like hell to get the prototype ready, and everybody needs to eat, right?
Depending on how he much he was taking, many could have a big problem with that.
