Please take into consideration the extra height of the basket though it is not much, causes strain on the the position of the body. The reach of the cashier is truly limited. If the basket it right in front of the cashier not a problem but most of the belts are accessed from the right.
The money tossing and rolled up money are indeed another problem and if the changed was placed on the areas where people that are paying put it there would easily be concern for the customer.Money must be straightened to go into the register drawer and also blind customers fold money a certain way so that they know the amount of each billl in their wallet. Their money is always straight when they give it to you.
Cell phone use in stores should be banned in the checkout areas. Phone use in the store by cashiers are for conducting store business and not for pleasure.
