I think they should simplify the pricing into easy to add numbers and drill the workers on adding in their heads. It's excruciating to watch someone add up $1.75 + $4.50 + $2.75. "I can do that in two seconds and I just want to scream $9.00!!!! It's Nine Freakin' Dollars!!!!" In the meantime, they have fat fingered the calculator twice and had to start over. Your french fries should not get cold in the time it takes to tell you what your order total is.
