Previous place the common thing for unlocked and unattended IT machines was to send an email to the IT Manager professing Undying Love (male or Female - didn't care) and then the IT Manager would reply with the usual "that's nice but no thanks", we would have a laugh and Prat with elevated privileges would maybe learn a valuable lesson - Not.
Of course, then the Manager inevitably left his machine on and someone decided to send the message to the CEO instead who didn't have a sense of humour.
Cue uncomfortable conversation with the CEO about the IT security policy.
