3 Victorians go to the shops to escape the constant drizzle outside. While inside, they each put in $10- to buy an umbrella.

The checkout chick isn't too smart, but soon realises that she's overcharged them. She runs out to hand them back $5-. Seeing that they are wearing Cobra jackets and figuring that they don't need all the money back, she puts $2- in her pocket, and gives each of the guys $1- each.

So, the guys paid $9- each ($10- outlay, less $1- returned)
Checkout chick pockets $2-

3x $9 = $27
1x $2 = $ 2
TOTAL= $29

Where'd the other dollar go?????

Who's in control of the abacus now!?!
