Average Retail Customers for a Bank & Uploading Cut sheets

The project that I am currently working on is a bank that has bathrooms in the lobby for client use and employee bathrooms in the office space behind the lobby. I am trying to figure out the following: 1) As I don’t know the exact number of retail customers I am using the default values out of the EBOM reference guide and have selected the .67 value for small retailer. My question is if I should use the square footage amount of the lobby as that is the only place the customers have access to or should I use the square footage for the whole building? I would also like to know if I was correct in choosing the small retailer value or if the service value would be more appropriate for a bank. 2) Do I only upload the cut sheets for the fixtures that were not compliant with IPC/UPC code, or should I upload all of them regardless?
