[Request] Please fix patients leaving while/after being tested/diagnosed

It's beyond frustrating to see patients leave while tests are being run or after they have already been diagnosed.

I get that someone waiting to see a doctor might get up and leave after spending half a day in the waiting room. But a patient who has already seen a doctor and is getting tested or has already been tested and diagnosed correctly just leaving is totally unrealistic. The patient is sick and wants treatment and is not going to just leave because he or she has to wait another 10 mins to see the doctor again and get it.
Not to mention that it doesn't matter whether the patient actually gets final treatment, the clinic/hospital did tests and/or scans and the patient would still get billed for those.

Please, please, fix this silly AI behaviour.
