Aibu to buy my boss the crappiest pressie I can find?

[spectacularvelvet]

History : boss and I don't get on much - long story , huge back history but bottom line - she's cold and difficult.
This year I'm tasked with getting her pressie after a whip round ... LIGHTHEARTED.... got £21 ( doesn't say much from a team of 12 eh?) ... what shall I get?

One of these ?

voucher and let her buy her own gift in the sales. Everyone a winner.

Fill this with rubbish stuff.

She gives everyone a gift and historically we've always got her something. I've had much hilarity reading all of these ... I did get her a very respectable pleasant useful gift - boringly can't say what in case it outs me
