PLEASE MAKE THE "NON-SUFFICIENT" CREDIT CARD TRANSACTIONS STAND OUT FROM THE REST!!!

If a transaction does NOT go thru for whatever reason - Please make them look different in some way - either change the color to red or have in HUGE letters that it FAILED....or .....??? Because it was the same color and "insufficient funds" was written so small, our receptionist missed it and we only caught the mishap AFTER the client left.

ALSO, while we are discussing "cc transactions" - It would be nice if you can keep the refunds, cancellations, etc (any altering of transactions) reserved for only staff that are authorized to do those things. We are having the newcomers "playing around" and end up cancelling transactions that shouldn't be. They are told not to "play around" but keeping that as a limited option would be a great way to ensure that they would not do that.
