"I suggest, I'll send her a short-hand message that she's been redirected. If that'll do, one of the guys has to sacrifice himself as a fake customer. I doubt, we can't find someone for that task.
If something goes south, we need to abduct her, Laes her, and dump her somewhere.
Or shall we do it like this either way? If she comes back to work next day and no-one remembers having cancelled the job, it might raise suspicions. Then again - drugging her will definitely raise suspicions too. Maybe the redirecting is more subtle, after all."
