Maybe I was unreasonable? I don’t know. When the customer asked the question about social media I was busy selecting one of my auto responses for explanation of rights, and highlighting the internet portion. When I came back I saw their second response and decided to say something else.
I feel like in this situation the customer should politely say,
“Sorry, but this is out of my price point!”
