I am not making any statements for what I think prices should be on a damn thing, but it is indeed the buyer who sets the market price. A seller can ask what the heck he wants. You have the buyer has the dollars in your hand. You determine if something is worth the price being asked. If something is being offered at a price you think it is worth, buy it, if not, don't.
WHat market? One seller is not a market!
It is the SELLER in a monopoly environment that determines the price. Or you think the 930 does not determine the price of the beer they sell? Since there is no possible competitor its a "take it or leave it" situation.
You are WAY too angry to have an intelligent discussion on this topic. The fallacies in your argument are numerous, starting perhaps with invalid premise and continuing to irrelevant conclusion and straw man. Others as well exist. It really boils down to one simple thing. If you think someone is charging too much, keep your money in your pocket. If enough people agree with you, prices will change. End of story. I'm out.
People are going to buy beer at rock shows regardless of price. People will often buy something even if they think they are being charged too much.
The fallacies are on your side my friend: 1) there is no market for beer at the 930, 2) Just because people buy something doesn't mean they don' think they are being charged too much. Or you've never overpaid for any item in your life?
The fact that people buy something doesn't make gouging right.
Anyways, to me this thread is about scalping and I said as much that beer prices are not really relevant to that discussion.
