COMMISSARY, PX

post exchange

(Abbr. PX)

A service mark used for a store on a military base that sells goods to military personnel and their families or to authorized civilians.

Meaning #1: a commissary on a United States Army post
台灣大學有一稱為「小福」的，應該成為「小福利社」樓：三層樓，還分租給近十家廠商當販賣、服務處（如郵局）。

其實應該稱它為「郵局」比較恰當。不過稱為「小福」也沒關係。

比較有趣的是它的招牌英文為 SHIAO FU commissary

這commissary 似乎有點對，可是，又怪得很！請問你有無更恰當說法？
我查一下：

commissary
noun [C] US
a shop which supplies food and goods, especially to people in the army or in prison
