I would consider paying with cash again IF $100 bills weren't so much trouble.
It's hard to get a $100 bill. ATMs just don't spit them out. Many places refuse to take them. It's just hard to carry over $100 in cash without quickly having your wallet explode in size.
Back in the day $100 was like caring $1,000 now. You could get a lot done with $20 bills... You can burn through the majority of $100 just going to dinner and I also have no desire to manage all that cash at my house or hit up an ATM every other day.
