Helped clients set up an LLC, then S status, back in 2013 when they acquired an ice-cream franchise.  Applied for and received the EIN online.  Today they asked me if I still had a copy of the SS-4, because DoorDash was not going to pay them their money until they saw it. 

My project this summer was going to be cleaning out old files.  Yes, we scan some of them, but a 10-year-old SS-4?  I found it.  Next question:  People order ice cream through DoorDash?  Really?
