Tonight I walked over to my local beer outlet in Davis Square, Downtown Wine and Spirits, to return empties and buy more beer. I really like the selection at Downtown, but they are a pain to deal with regarding empties. Like many liquor stores, they have gone to the freakin' redemption machines that turn what should be a really quick transaction into a drawn-out process of shoving in bottles one...at...a...time. Downtown is also slow to update the machines when they add new brands, with the result that you have to return some bottles outside and then get on line to return the rest inside - where they take them rather grudgingly.
Tonight, the machine was just flat-out down, and when I took the bottles inside, the guy behind the counter tried to tell me that I'd have to come back once the machine was repaired. I got pushy and got him to take my bottles - but the confrontation sucked.
SO - when I got home, I checked on the law. Here's a part of what the Massachusetts state government site has to say about the bottle bill (I've added some emphasis at places):
A retailer is only required to accept 120 containers in one day from any one person, but may choose to accept more. There is no similar restriction on redemption centers.
