IN the early 1980s, while I was living in the US, I did a summer school in Maine. In those days, many of the pubs had great big vats full of boiled lobsters at $3 or $4 each.
I've never heard of such a thing. Granted, I wasn't going to "pubs" in the early 80's (I was born in '75) but whoever heard of lobster in a bar? And does he really mean "boiled lobsters"? Here in Maine, many places have lobster tanks with live lobsters, from small Mom and Pop's type general stores to large grocery stores (and they aren't particularly expensive here), but I have never seen or heard of places having a big vat of them already cooked and on demand. That doesn't even make sense; whatever doesn't sell at the end of the day wouldn't be good for much, or, who would want to eat a lobster that was cooked in the morning if they arrive at night? Even restaurants that serve lobsters don't cook them until someone orders one.
I've only had lobster once in my life and it was pretty good, but too much of a hassle to eat. I've never been tempted to buy a live one even though you see them everywhere around here.
