Interestingly, XIX century Poland has exactly the "minimum amount consumed" kind of quotas of alcohol... It was legislated by nobles who were producing alcohol from their grain and figured they'd force peasants to but it from them, to periodically extract whatever monetary surplus the peasants (serfs) managed to build up. One of the result was of course rampant alcoholism, since the peasants now owned buckets of vodka and they figured they might as well drink it if they paid for it...

I think quotas work in both directions.... you have to do this many in certain time, or you only get this many in certain time.

Here is the definition....

:a proportional part or share

especially : the share or proportion assigned to each in a division or to each member of a body

I always understood a quota to be a limit. Only in sales have I heard it used as you describe. For example look at EU milk quotas.

Depends. I clicked through to read about mandatory alcohol consumption, but thinking about it further, consider the case where you have "1 GB of disk quota". In that case, it obviously means that you can use no more than 1 GB of disk, it definitely doesn't mean that you must use 1 GB of disk.

I only know this from AWS, where it means "limits".
