The Infinite Soda Supply

A seemingly endless supply of soda,
whenever played, you may generate one
soda card per turn.
"No matter how many sodas were taken,
or how many people were drinking them,
the soda supply remained stocked....at no point
during the week was the supply replenished.
It leaves us all wondering just how many sodas are in there, how they all fit, where are they coming from,
and if they are ever gonna run out."
