So what’s the deal with bakers?

If a "baker’s dozen" is thirteen, that’s way less useful.

There are a few theories as to how a baker’s dozen became thirteen.
关于“面包师的一打”是如何变成13个的，有几种理论。
But the most widely accepted is that bakers would throw an extra loaf into orders of a dozen to avoid a flogging.
但最被广泛接受的做法是，面包师会在一打的订单中多扔一条面包，以避免被打。
In medieval England, there were strict laws controlling the price of bread.
在中世纪的英格兰，有严格的法律控制面包的价格。
Bread had to be priced in relation to the price of the wheat used to bake it.
面包的定价必须与用来烘烤面包的小麦的价格挂钩。
If a baker was found to have cheated by shorting their loaves, things could go badly for them.
如果一个面包师被发现做短面包做弊，事情可能会变得很糟糕。
And "badly" in medieval England meant...they could be fined or even beaten.
而“糟糕”在中世纪英格兰的意思是，他们可能会被罚款，甚至被殴打。
Human rights violations aside, the big problem with these laws was that even careful bakers make mistakes.
撇开侵犯人权不谈，这些法律的最大问题是，即使是细心的面包师也会犯错。
Variations in rising, baking, and air content could all change the size of a loaf and made it hard to be sure it was the planned weight.
蓬松、烘焙和空气含量的变化都会改变面包的大小，使人很难确定它是计划重量。
And some bakers didn’t even have scales to weigh their dough on.
一些面包师甚至不用秤来称他们的面团。
Afraid of accidentally coming up short, some bakers would just throw an extra loaf into lots of twelve.
一些面包师担心不小心缺斤少两，就会往一打面包里再扔一条。
The extra made sure they were staying within the law-- and avoiding a flogging.
这条额外的面包确保他们遵守法律--并避免鞭打。
Some bakers even used fourteen instead of thirteen for a dozen.
一些面包师甚至一打用14个而不是13个。
Better safe than sorry, right?
安全总比后悔好，对吧？
Mathematically, twelve is probably still the better value for a dozen.
从数学上讲，12可能仍然比一打有更好的价值。
But now you know that bakers had their reasons.
但现在你知道面包师有他们的理由了。
