Apparently some guests that checked out today paid with a Check, but they (the people at the front desk thisyesterday morning) posted it as a Mastercard payment on each room. Now I have to fix it, but I can't unless I verify that we actually do have a check. Maybe I should just assume we do have one and credit the MCs back. But really. Don't leave a mess for someone else to clean up.
This illustrates exactly how I felt when I came across ^this.
I've got to move all those guests to House/PM (Posting Master) Accounts in the computer, extend their stays till tomorrow - when I can hopefully verify we have a check payment for those rooms, then settle everything so they can be checked out of the system.
