Yeah, I wasn't entirely clear regarding that. What I meant by "take longer" in the video is that if you spam the button to exchange, every time he would have given you something else, it will say you need more slots. However, if you would have gotten a fuel cell, he will still give you it, since they stack. So you have to spam the button because the "you need more ETC slots" will most likely be a lot higher than the number of fuel cell exchanges. The upside is that you'll only actually EXCHANGE the badge if you do get the fuel cell. It's tedious, but it works.
Really enjoyed this video!
You said that if my ETC tabs were full, it would either give me the two fuel cells, but it doesn't let me and says my ETC tab is full.
