The Sinn Fein leader criticised the government's new rules for restaurants as "nuts" and "a bit wacky".
Businesses will now have to keep a record of what meals a customer ordered for 28 days.
It's so Gardai can make sure a pub or restaurant is serving food and complying with Covid-19 regulations.
Mary Lou McDonald doesn't think it's the right approach, "This business of keeping records of 'did you have jelly and ice-cream or did you have apple pie' is just not the place that we should be in".
Restaurant groups say they weren't consulted about the changes - and pub representatives say it's "bureaucracy gone mad".
The Irish Council for Civil Liberties says 'This level of surveillance extends far beyond human rights norms and what the law allows'.
However, Minister Simon Harris has defended the new rules.
He admits that there's been a lack of clarity around the issue, but says that establishments are simply asking to keep a copy of the receipt, 'The government doesn't care if you change from the garlic sauce or the pepper sauce but how do you enforce it if there can't be proof'.
