Fate intervening on my behalf?

Today a small payment from a client cleared that really should go towards a bill that I have to pay.  It's not a large amount but it's enough to pay about 50% of a bill that once it's paid will be gone.  Well, I drop the little ones off at school and tell myself that I'm starving and I'm going to treat myself to McDonald's.  Nothing too fancy, just an egg and cheese biscuit and maybe a carmel frappe.  It would cost me about $6 which isn't a lot but it's $6 less I would have to put on this bill.  I drive to McDonalds, get in line and get ready to order and decide to check my purse and guess what?  I left the debit card at home.  I have everything in my person, my wallet, all my other crap but the debit card isn't there.  I know it must have fallen out on my bedroom floor.  So, guess what?  No McDonalds for me. 

I drive home, go inside and decide to make myself an egg omelete with a cup of tea instead which cost to me is ZERO!  Now, if fate could just intervene like this everytime I went to spend money that I shouldn't how much easier things would be!
