It is something of a similar issue for UK restaurants. Alcohol has traditionally had a high profit margin, so reductions in consumption will hit overall profits disproportionally.
I used to poopoo the blue laws in my “chosen” state of residence until I learned to embrace BYOBs.
Cuts our bill in half, easily.
We only go to BYO restaurants also.
I don’t mind paying extra for food, but I refuse to pay triple the price for a bottle of wine. You can buy a bottle of wine for what they charge for a glass. These greedy restaurant owners have no one to blame but themselves.
We kind of stopped drinking anything other than water when dining out. I may have a beer every two or three months, but that’s about the extent of it. We tip well, but no restaurant is making bank on us, at least as far as beverage mark-ups are concerned.
A quick Google tells me those are laws restricting alcohol on Sundays.
There used to be similar in Wales, the last local ban disappearing in 1996. Back in the 1950s, it was very common but I remember Dad telling a couple of stories. First was that, whilst pubs had to close, the ban didnt apply to hotel bars. So everyone went to the hotels on Sunday. Second was that he knew of a pub where the boundary between two council areas, which had differing rules, ran literally through the pub. Meant they could open one bar but they couldnt use the other.
When I first moved here, liquor stores were closed on Sundays. When that law changed we had a handful of concerned xtians protest in front of the state stores 
As if folks couldn’t already buy all the booze they need on a Saturday, but logic doesn’t play into that kind of magical thinking, I suppose.
And then here in the U.S. there’s 'Dry" States like Kansas where I was for 3 years. The Name brand beer is 3.2% by law. Hard liquor was available only in “Private Clubs” you had to be a member of… so you walk in, give the bar tender a buck & now you’re a member. 
Some counties were dryer then others. Note this was 50 years ago <–(every time I say that it’s a GAH! moment, where the Hell did it go???) so things may have changed. 
Liquor laws in the US have been a complete mess since Prohibition ended.
We still have these in the US, and they restrict more than just alcohol. In parts of New Jersey, malls and retail shops are closed on Sundays (grocery stores can open) and some states restrict the sale of automobiles on Sundays as well. They started as a way to promote a day of rest, but in this modern 24-hour society we live in, where many households no longer have one spouse stay at home, they seem very impractical.
Also, Sunday is not everyone’s “day of rest.”
In Germany, most all stores are still closed on Sundays.
That is true, too. Not everyone works M-F 9-5. Some (of us) work multiple jobs every day.
i was actually referring to Sunday being Sabbath for Christians (not Jews or Muslims), but your interpretation works very nicely also.
Besides being a heathen, I was also thinking of my friends in the hospitality biz, whose day off is often Monday or Tuesday.
