In NY I'd rob a Starbuck's rather than a Waffle House.*None* of the customers (or staff) will be armed and they'll be carrying more cash.
You’d have to put an AK to my head to get me into that metrosexual, overpriced, fruit loving, left wing establishment.
but you’re right. no guns and lots of money.
They might not have cash, or even credit cards, just Apple Pay via their iPhones. You could steal their iPhones, but Apple makes them useless to you.
