NMC client spreadsheet

I created an excel spreadsheet listing all our clients, titled, "student info" in the NMC Documents folder. I have them alphabetically listed by last name and I inserted 3 columns (-1, -2, -3). We are initiating the 3 strikes yer out rule. So when someone is late, we cross out the column. Three times late? Their row gets turned red. Red the color of anger...and the color I turn when I have to tell someone their camera has not been returned so their reservation is cancelled.

So please when someone comes in to check something out, cross reference their name with the one on the excel list to make sure we have their info (and if not, add it), explain to them our late policy and confirm they know how to use the equipment.

Thank you.
