I Didn't Ask for Shortbread

I go up to the vending machine yesterday in search of a tasty snack. The display looks like this:

A 0 6
B 1 7
C 2 8
D 3 9
E 4 10
F 5 11
G
H

Simple enough.

Dollar #1
mmmm... Boy, a Twix bar sure does sound good right about now. Let's see here.. Ah yes, F-10. So I take my finger and press F and then I go for the "1" and "0" combination. That was wrong. I ended up with F-1's crappy shortbread. Ok, it's only 65 cents down the drain. I'll try again.

Dollar #2
In goes the fresh dollar. "F"...."1".....DAMMIT. Out comes another shortbread. Let's see where we stand:

Shortbread 2
Twix 0

Any other person would have stopped at this point and settled for 2 packages of crappy shortbread. Not me. I whip out another dollar.

Dollar #3
Third time is a charm. "F"...."1"..wait, no "10". oh boy...more shortbread. My attempt at correcting my mistake only made me look like a fool in front of my boss, who is now laughing at me. Now I'm holding 3 shortbreads in my hand and I'm blaming the machine for not knowing that I wanted a Twix. How could it not have realized that I changed my mind last second? What an asshole.

Dollar #4
Why am I still doing this? "F"...."10"....yes! OH GLORIOUS DAY! Down falls the Twix, up goes my mood. I leave feeling like I have just won a fricken gold medal. The machine was trying so hard to not give me what I wanted, yet I outsmarted it, and was victorious. Take that vending machine.

I didn't even finish the Twix. It was gross and I threw it out.
