I think if that were the case and someone - MG or anyone else- would have ensured that the client details record was completed in accordance with office policy.
The fact that the particulars (of budget, personal details, ability to proceed etc) were NOT recorded is another red flag supporting the hypothesis that Sjl herself invented the appointment as a cover for something, imho. Then again, perhaps she was just too careless, or too lazy to record them. Or perhaps office protocols were not so tight as they should be.
