Noooooo it's not a millenial thing to eat late. I used to eat late when leaving the bars at 4 a.m. when I was in my 20s living in Florida. I still eat late when in New Orleans. But even if you are a millenial, you too will outgrow this thing of eating late and craving food, LOL (maybe?).
Five Guys is not worthy of freezing. It's pretty good but not great. I never do one at base pay, I always need a bonus to do one of those shops. And forget the fries. I have tried to take them home for reheat in the toaster oven, just not that great.
