The gift needs to be able to come off as a genuine gift so there’s some plausible deniability…
Edit: Just so it’s clear, this is purely hypothetical. I just thought of the idea and thought it would be funny to see what a random person on Lemmy might think. This isn’t a serious request and none of the suggestions will ever actually be used.
The cheap brand of something they know is crap. Say they are into water colour painting, get them the cheapest set you can find on Amazon, but not so cheap that it looks like a kids gift.
