Funny real world opposite example:
I appointed an estate agent to find me a tenant. They found one, so I needed to pay them. They needed to generate an invoice so I awaited this to obtain their bank details to transfer the money.
The accounts lady generating the invoice phoned me and asked for my bank account details. I explained they don’t need my details, I need theirs as I am paying them. She replied that they needed my bank details for AML purposes and if I don’t provide them, she cannot produce the invoice.
I replied, “so I guess that concludes our business then?”
At first she didn’t understand, so I repeated the statement.
I think they understand now.
