When I was a kid, I misheard that part as "to even help the store" - another show, The Superhuman Samurai Syber Squad contained a song with the same lyric, which I misheard as the same thing.
I took it to mean that the Power Rangers (and the Syber Squad) are so heroic that they'll even do simple helpful tasks, like help out at the store/shop. I may have also thought it was a legit figure of speech since two shows I watched used it, like it was something people say - "You can even count on them to help the store."
Also, the first movie might have been one of the earliest moments (if not the first) when I was aware of a franchise having more than one "canon" - I saw the movie before the Ninja Rangers era, and was at least mildly confused that the Rangers got their Ninja powers and Zords in the show a completely different way to how they did in the movie. When I heard that they were going to include the Ninja Rangers stuff in the show, I assumed that the Rangers would just remember the events of the movie, and be all like "Wait, we've still got those powers..." and then use them, but instead they did a whole other storyline on how they get them (as the movie wasn't part of the show's canon, or maybe it's "non-canon" - I dunno.)
I actually remember that I distinctly thought that Adam would be the one to remember and point out that they got those powers/Zords in the movie.
