We need to be able to put our guests service and product purchase on hold. It is very frustrating when we set up a charge for a guest, either product or a price change and it goes back to the original if you do not remain on the purchase screen. Or if it is not cashed out that day it disappears. If someone forgets to cash out their guest there is no record of what they were supposed to be charged or bought. If we had a hold in the purchase area this would be very helpful.
