Separate PK in Jxn Tbl?
Does a bottle of Gin have a serial no? I am too poor to buy 2 at a time to see if there is a different number Ah!
In the US, you get a UPC/EAN code and then a batch number with booze.
The closest thing to a serial number is your cash register receipt.
Now if someone will explain to me why we have expiration dates on salt
and bottled water to me because I don't get it.
