If you have giant hands, you probably find it difficult to reach into the can past the halfway mark, right?
The other problem you have is your natural human tendency to cram several chips at once into your face. There's no shame in this, but you can train it out of yourself.
With my patented technique, it's impossible to eat more than one at a time. Plus, it limits the number of times you have to reach into the can and potentially kill yourself or other motorists.
First grab a large stack.
Here's a shot of the proper finger placement.
With your middle finger, deal a chip from the bottom of the deck like so.
No matter how hard you try, you will not be able to deal more than one at a time, thus forcing you to moderate your natural gluttony.
Now just lift that hand to your face and snap up that bottom chip. No constant reaching anymore!
