The sales tax rate in Rubenenkoville is 6%. During a sale at the Bergville Coat Closet, the price of a coat is discounted 20% from its $90.00 price. Two clerks, Jack and Jill, calculate the bill independently. Jack rings up $90.00 and adds $6%$ sales tax, then subtracts $20%$ from this total. Jill rings up $90.00$, subtracts $20%$ of the price, then adds $6%$ of the discounted price for sales tax. What is the value of Jack's total minus Jill's total?

Let's think step by step and output the final answer within \boxed{}.
