How much cash have you wasted

[jokerthief]

The other day I was at Mcdonalds and ordered a double quarter pounder meal. I soon realized that I would have much prefered two double cheese burgers, so I wasted $3. I then began to think of all the times I've ordered more food than I needed, bought 1-5 more drinks at the bar than I could really enjoy, the classical guitar book I thought I would study, the Pantera WhiteZombie concert I went to even though I didn't like either band, ridiculously large drunken tips I've given out, the 50 books I've bought and haven't read, all the cigs that I've smoked for years before I quit, ect.

I bet I've wasted 20-30K over the course of my life. How much do you OOTiots estimate you've wasted?
