Blue Laws suck. They were put in place becauce the bible thumpers thought they knew what was best for everyone.
I live near Dallas and when I got here the Blue Laws were in full force. You'd go the the grocery store on Sundays and the beer section was chained off. They had isles roped off for products they could not sell.
Interesting, you could go the the hardware store and buy a hammer, but no nails. You could buy an aluminum ladder but not a wooden one. You could buy cheese but not a cheese slicer. Go figure.
The malls were closed all day. Even now the car lots are required by law to be closed one day a week. Most places opt to stay closed on Sundays, which make the bible thupmers happy I am sure. There are still some stores that stay closed all day.
I have noticed that since the early 80's the laws have relaxed a bit. Due in part because of us Yankees moving down here. We pitched a fit loud enough the lay makers had to listen.
There are still "wet" and "dry" areas unfortunetly.
You have to have a membership card to get a beer or any alcoholic beverage. A huge problem was that you had to have a membership card for every restaurant or bar you went to and at ~$5 each it got expensive. Even if you went to a chain restaurant the card was good only at the location it was issued at.
They finally came up with a UniCard which was good every where, one card one fee. That was until restaurants stopped accepting them and again mandated you had their card.
Since Texas is deep in the heart of the bible belt and actually I think this is where the buckle of the belt is, things will suck for quite a while.
