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.
One trick I heard is to get them a gift card towards a Las Vegas vacation. If they go to Vegas they are way more likely to lose money than win at the tables.
