"Cash Register" bonfire bug

[letalumil]

In the following test-case expected ['TWENTY', 80.00], but only ['TWENTY', 60.00] available.

assert.deepEqual(drawer(3.26, 100.00,

[['PENNY', 1.01], 
['NICKEL', 2.05], 
['DIME', 3.10], 
['QUARTER', 4.25], 
['ONE', 90.00], 
['FIVE', 55.00], 
['TEN', 20.00], 
['TWENTY', 60.00],
['ONE HUNDRED', 100.00]]),

[['TWENTY', 80.00], 
['TEN', 10.00], 
['FIVE', 5], 
['ONE', 1], 
['QUARTER', 0.50], 
['DIME', 0.20], 
['PENNY', 0.04]],

'return correct change with multiple coins and bills');

I'm going to fix it and make a pull request.
