Not really much of an issue for me.
I just stop playing or pause the game while I eat something, either that or play a few cutscenes if possible to watch while I eat. There were a few times in the past where I asked a friend to take over playing while I went to go grab something I was already cooking, but nothing in terms of "take this while I go get something to eat".
Step right up come on in, feel the buzz in your veins, I'm like an chemical electrical right into your brain and I'm the one who killed the Radio, soon you'll all see
So pay up motherfuckers you belong to "V"
