Severely misinterpreted exopression... the original was derived from an unfortunate situation in the 1920'
s, when a tired shop-keeper decided to take a
nap while standing behind the counter. A customer came over to him, asking the price of the bisquits...when the shop-keeper wouldn't repond,
the man nudged him, and the
poor sleepy man mumbled "I'm-a-dozing". Unfortunately the customer heard "dime a dozen" and the shop-keeper lost some goos bisquits that day...mm...bisquits.
