I worked at an Arby’s back in high school (over 20 years ago). They told me free refills were a thing because most customers don’t refill more than once, if at all. Also, the soda water costs pennies and the bags of concentrated soda syrup were only like $10 (at the time). A single bag of syrup, mixed with soda water, could fill customer’s soda cups for maybe 2-3 days before it needed to be replaced. Fast food restaurants make insane profits on soda, so they don’t care if customers refilled multiple times during their visit.
I got into Pokémon when the card game and anime first came to America. I was in jr high school at the time and collected so many of the original cards. Never finished my collection, though.
I got into the Pokémon craze at first, but stopped following it in my later years of high school. I was too busy preparing to be an adult, so I set it aside and forgot about it for years. I didn’t even know there were more than 151 Pokémon until over a decade later.
I learned some of the newer generations with Pokémon Go, but I still remember all of the original 151 Pokémon. The newer stuff is just weird to me.
EDIT: I never got into the games, even though they started releasing when I was a teenager. Pokémon Go was actually my first game in the franchise; although I watched my friends play the classic Red and Blue games back in the day.
