Bill stamped with different message ( french )

I found a bill today it is stamped with
Paye
par un travailleur
du Tabac

Anyone care to translate I know a couple words.. but not what it really all means

Pay by a worker of the Tobacco. I used the site below to translate.

Why would a person stamp a bill with that?
doesn't even make sense.

maybe it was a different type of tobacco and they had a lot of it? for years?

I think it has something to do with workers in the cigarette industry…the conotation likely refers to a union of some kind. Was 'Tabac' capitalized?

It was stamped 2 times on the back of the bill. in red it is not capitilized in blue it is.

another question for the populous
With this message stamped on the bill, would you stamp this bill with your money tracking stamp??

It traslates to "Paid by a tobacco worker"
