When I was a teen liquor stores in Mass closed at 11 pm Saturday and could not re-open until Monday. The law resulted in the reverse of the desired effect, as everyone overbought 'just in case' before the package stores closed on Saturday night. This was back when blue laws were still in full effect, with retail stores all closed on Sundays. In the mid-70s the legislature started finally making some concessions such as letting malls open on Sundays between thanksgiving and christmas. If you missed out and wanted beer on a Sunday your choices were a bar, drive to NH, or find a friend who had served in the armed forces to go to the naval air station in Weymouth to buy for you.
In the early eighties I recall going to Connecticut on business trips, and if you wanted beer or liquor from a store, then you had to buy it before 8:00 pm. There were lots of dry towns not far from Boston (Needham and Wellesley come to mind; I'm sure there were plenty of others) back then. I was genuinely shocked to find that a dry town was actually something happening so close to where I lived; at that time I thought dry towns were strictly a thing from podunk deep south towns, and had no idea there were dry towns in eastern Mass.
