Thanks all..mrkmorin one of the issues with the re-opening of a tab is that there is no "manager on duty" most nights. It's that small of a place. The POS system was actually put into place to help combat theft. It helped us ferret out a problem employee who we have let go. I watch the open orders very carefully to look for trends but as of now it looks arbitrary and is not nearly as common.
It did happen once last night again though, server A opens a tab for a regular customer. Customer has a couple cocktails that all end up on the tab and settles up. server A accidently puts cash instead of card on the ring out process and the check closes. She re-opens the check zeroes out the payment (wasn't there so I don't know how she did this) and then settles it again with the credit card, this time it stays open. The receipt shows a $14 total, paid with a card and an amount due of $0.
My question is, should this have closed when settled or now, since it was a re-opened check, does it always have to be closed manually? Our batch runs at a certain time on it's own. I checked and that charge is in the batch.
