On the Day your in Court to give evidence
If a passenger is up before the wig,the evidence of the Garda will be enough....i certainly wouldn't be attending any court cases.
A passenger has a reasonable excuse to not wear a mask if they have a medical condition. A taxi driver has to make a reasonable effort to make the passenger wear a mask.
Taxi driver: Please wear a mask.
Passenger: I have asthma/COPD.
Taxi driver: OK, I'll need to confirm your story with this FN-supplied lie detector machine...
I don't think the Guards/Judges will expect us to do step 3?
