When a server using a “staff bank” closes out the staff bank, the closing report will ask for an amount of cash due from server. This amount, as I understand it, is the amount of cash sales, minus any gratuities. However, sometimes the gratuities are larger than the amount of cash sales, and the report states an amount that is owed to the server. My question is this – does the POS automatically subtract this amount owed to the server from the total cash on hand?
