If John and Suzanne are right and the cause is inadequate fixing (I wouldn't know!) then it could be that the lab is overusing their chems and on this occasion your films were the last ones through the fixer... In any commercial operation there is always the temptation to squeeze as much as possible (or more) out of any material used. I think it highly unlikely that the lab will admit it though.
Now you're souping your own it's academic. Congratulations on making the leap and all the best for your new darkroom!
