Actually here in Ontario, despite shutdowns, schools have remained open. I think Schools are being quite militant about not allowing any child that's sick to be in the school. Note in the Ontario COVID-19 thread some posters are decrying this as a potential room for more outbreaks.
But also note that Children usually don't live in Silos, they can come home and spread the disease to parents or grandparents.
Churches are large indoor gatherings. Much like sporting events.
Liqour Stores are much like any other form of commodity retail like Grocery Stores. People need to shop to continue the economy. Though in some places, even retails has been shut down or reduced.
I think you can appreciate the social issue generated by banning alcohol sales as well.
People really shouldn't be gathering indoors in large numbers. We can see that the biggest spikes in cases are coming from places where multi-generational homes. These gathering are difficult to enforce. Which is why numbers keep going up. Especially when winter weather drives people indoors more.
In Toronto indoor dining has been suspended for a month. You can get McDonalds using the Drive-Thru. I'm sure you're not obstinate enough not to realize that.
I'm sure BBQ Boy could have still remained opening by offering Take-Out and Delivery. Not saying that's ideal, but it's all a goal to reduce indoor public gatherings.
I had take-out this week at a restaurant that has directed all their resources into offering take-out and delivery. Dining elements are all closed, even though they're technically allowed to be open where I live.
That's highly anecdotal as I don't know where you live.
