It seems to me that it's kind of haphazard... I never know when to expect them. Fortunately, I do a lot for them and I usually get a personalized email asking if I would like to do a shop or two for them. I love them... they are really nice and they pay so quickly! Plus, it's hard to say no to the burgers their client serves!
