Goal:  Allow guests to see transactions as they are rung to prevent internal theft

The key to proper placement of a point of sale terminal is visibility.  You want to set up your terminal so that customers can see every transaction as it is rung up.  Many POS systems do a great job of displaying the transaction total in large numbers on the screen or display ‘no sale’ when the cashier hits the no sale key.  It makes it very easy to have a manager or supervisor monitor the transactions from accross the restaurant.  If your terminal is in a position below a counter, add a display arm or ‘goose neck’ to your POS.
