You can’t teach an old dog old tricks

I do design work for a small print shop and the owner/my boss is not old per se, but he absolutely
hates change and anything to do with technology. He regularly has me run credit cards and scan invoices for him because he doesn’t know how.

Me: You know, I could show you how to do this. It’s pretty easy.

Client: No thanks, I don’t want to learn anything new.
