Bill size does matter

How many of you carry cash anymore?  I  hadn't for the longest and found myself relying on that piece of plastic in my wallet.  I was using plastic for everything and then the bill came and I was unhappy at the balance.  Well it was because I was using my credit card indiscriminately.  Okay, truth be told, we both were.  So The Man and I did something radical.  We now head to the ATM weekly and take out our "allowance."  That is the money we need to use for those trips to Starbucks, Chick Fil-A (shhh...don't tell anyone), or to pick up the bottle of chardonnay I can't live without.  We aren't perfect on this account.  Sometimes we run out of allowance before the end of the week and reach for the plastic.  I probably do it more than The Man since I know there is always a buffer in the spending plan hehehe  

What got me thinking about this topic was a conversation today with a couple who I am friendly with.  The husband was hesitating before giving his wife a $20 bill for the snack bar.  The hesitation was because it was a $20 bill.  If it had been something smaller, there wouldn't have been hesitation the wife explained.  Once that bill was broken then all bets were off on spending the rest of it.  I laughed because I had just come across this article recently about how bill size really does matter  http://moneyland.time.com/2012/01/26/why-bill-size-really-does-matter/?utm_source=Jean%27s+Email+Newsletter&utm_campaign=251ca6f6e2-This_Week_In_Your_Wallet1_31_2012&utm_medium=email

So how do you handle your spending money?  Do you have a set amount?  Do find this very thing to be true in your case?
