You may want to have at least $5 in your pocket at all times.
More and more places are requiring a $5 or $10 minimum purchase to swipe your card. That means if you're buying less than the minimum, you'll need cash.
Credit and debit card companies charge a store what's called a "swipe fee" each time somebody uses a card, that's why they ask for a minimum purchase.
