> “hi there North American IP, I know how much you like extra hassle hence the love of effectively paying for tarriffs, here, have a little extra work on me!”

I'm assuming you're outside the US based on having this idea.

You might as well just say "I'm mad at your country for the tariffs, so here's an extra wait." From the fact you feel the urge to spite people in a tariffing country like this, it's clear the tariffs have had some negative effect on you, which goes against your narrative that they're "effectively paid for" by those in the tariffing country who voted for it.
