This very rarely happens in MA, because when it does the store has to give you the item for $10 off, including if that makes it free. And they have to post a sign at the register explaining the law, which means when you're invoking it all you need to do is point at the sign.

(That being said, even though I think it's a silly rule, it just seems to exist to annoy alcoholics who can't plan ahead. I'm not an alcoholic, and I rarely consume alcohol before noon, so I just laugh at people who whine about this law.)
I live in Massachusetts, the bluest of blue states, and we still have special laws about Alcohol on Sunday. According to Gemini, Logan airport can't start serving until 10 a.m. (Because in Massachusetts, we don't want you getting drunk on the way to your Unitarian or interfaith Sunday service after you get off of your red-eye flight.)

yes there are, but the anti happy hour laws are only from the 1970-80s, Mothers Against Drunk Driving, raise the drinking age campaigns.
the previous round of laws like that were from the Temperance, Prohibition, lifting of Prohibition periods.
then before that, yes the Puritan Blue Laws.
