Ever see that commercial from Visa where everything is moving smoothly untill someone holds up everything with CASH. That is exactly what I hate and I mean hate when someone in a line holds up things with those stupid dollar coins, two dollar bills, checks or even half dollars. I'm in the Chicago area where there are lines for everything, eveywhere. Nothing like being in grocery store line with frozen food in your cart and someone wants to be the one to spread those baby dollars so that the cahier has to call someone to see if it's OK to take them. I think the people that use those in lines should be charged an additional amount of money to pay for my melted Ice Cream.
Cashiers in Chicago must be illiterate. I've spend lots of dollar coins around here and never had a cashier do more than a quick look at both sides of the coin. Shop somewhere else.
