Once in a while an appreciative patient will wish angry doc well with a 'Have a nice day, doctor' or a 'God bless you, doctor'. And then once in a while a patient (usually the little old ladies) will wish him 'facai' (make lots of money), as one patient did today.
Patient: Thank you, doctor. I hope you 'facai'.
angry doc: No lah, doctors make money off sick people; we cannot 'facai' lah.
Patient: But you should - otherwise your heart will not be in it. If you get fame and fortune from your practice, then your heart will be in it.
angry doc: Er... OK. Thanks.
I'm still not sure what to make of what she said...
