: 前陣子玩遇到一個賣貨的狀況如下：
: 玩家A要賣一個需要兩桶啤酒的木箱到交易所
: 該交易所有兩個木箱的標記，且上面的公家啤酒皆尚未被消耗
: 此時的啤酒來源：
: 1. 只能消耗其中一個公家酒，另一個需要從場上取得，僅獲得一次交易所bonus
: 2. 可以直接消耗兩桶公家酒，並獲得兩次交易所bonus
: 我的傾向是1.的玩法，感覺上玩家必須選擇其中一個木箱標記做交易，因此另一桶必須

是1。我想規則應該寫得滿明確的。
規則書第8頁，賣貨的啤酒來源：
Beer may be consumed from any of the following sources:
1. Your unflipped Breweries (J). These do not need to be connected to the
location where the beer is required.
2. An opponent’s unflipped Brewery (K). These must be connected to the
location where the beer is required.
3. The space beside a Merchant tile that you are selling to (see “Action -
Sell”). When multiple beer barrels are required, each beer may be consumed
from a different source.
規則書第10頁，賣貨的步驟：
2. Choose 1 of your unflipped Cotton Mill, Manufacturer (C), or Pottery
tiles, that is connected to a Merchant tile featuring that industry’s icon
(D).
3. If there is a beer barrel (E) on the space beside the Merchant tile you
are selling to, you may consume this beer as part of the Sell action, and
collect the Merchant beer bonus (see “Merchant Beer Bonuses”).
……
5. You may go back to step 2 and repeat the process for each of your
unflipped Industry tiles (including those of a different industry).
a merchant tile that you are selling to, the space beside the merchant tile
都是明確的單數記載。
一個商品就是對應一個商人，不會對應兩個商人。需要兩個啤酒的木箱，若選擇賣給左邊
的商人，就是只能用左邊商人的酒，不能用右邊商人的酒(不論右邊商人是否同樣可接受
這個商品)。
需要兩個啤酒的木箱，兩個啤酒可以是不同來源沒錯 (合法來源包括來源1自己酒廠、來
源2他人酒廠、來源3商人)，但如果這個木箱是要賣給左邊商人(賣貨的步驟2是選擇左邊
商人)，則右邊商人就不算是合法的來源3。
到賣貨的步驟5，要賣另一個商品時，才會回到步驟2選擇另一個商人，同樣說明了一個商
品就是對應一個商人。

摘錄句子
If you are selling a good to a market that has multiple merchants that will
buy it, you can choose which merchant to use each time.
Each beer is associated with a specific merchant, not with the location as a
whole.
