A local senior living center is holding a "Nurses Night Out" event to coincide with National Nurses Week next week.  To thank them for their services, they will receive complimentary facials, chair massages, manicures, dinner, etc.  There are only going to be two aestheticians there.  Any recommendations on how to handle a crowd with limited time to perform facials?  Any thoughts on shortcuts and tips for events such as this would be greatly appreciated!
