user2785: On LiChess, FM knightprince gave a simul where I participated (our game).  I blundered a pawn played a pawn gambit, but managed to complicate things and won it back.  Afterwards, the game would have led to a drawn endgame.
The FM offered a draw; I wanted to refuse, but thought that would be perceived as ungrateful, so I accepted.  I wasn't expecting to win; I just wanted to play out the endgame for the experience.
Question: Is it bad etiquette to decline a draw offer when participating in a simul?

user31627: In the game linked in the OP, play would have likely continued 16...exd5 17.exd5 Nxd5 18.Nxd5 Bxd5 19.Rfd1. Black can try 19...Bb6, although the chances to create anything serious against the doubled b pawns are slim.
However, a simul is a team game. Accepting a draw means there is one less board for the strong player to think over. As a consequence, one should avoid accepting draws in simul games when the position is not a dead draw. I would argue, if anything, that accepting a premature draw is against etiquette towards your teammates. Of course, there is a balancing act - one more board is always good for the team, but playing on K+R vs. K+R as a time-burner board is quite rude.
Whether the OP’s position qualifies as a dead draw is not clear to me. I would certainly have played on a couple more moves, as I do not see much danger for Black after 19...Bb6, but taking the draw was probably reasonable as well.

user4399: It is absolutely not bad etiquette. If you do accept a draw, then you might regret it. Look at this kid's endgame against Wesley So in this South African simul (lichess for the position).
FEN: 8/6k1/6n1/p5P1/7P/8/2B1K3/2b5 w
[FEN "8/6k1/6n1/p5P1/7P/8/2B1K3/2b5 w - - 0 1"]

Look at not just the current position, but even the previous position. Black had just played Ne5g6. Look at the evaluation in of the previous position!
On the other hand, you may end up like Misha Osipov vs Anatoly Karpov.
I myself think to ask a separate question like 'Is it bad etiquette to ask for the move to be made?' or 'in a simul should draw offers be made with a move?'

user12873: No it's not bad etiquette at all. A player being higher rated does not entitle them to automatically get the result they want, even if the position seems to indicate such a result.
And in the rare case your opponent gets offended by this, congratulations. You've just gained a psychological edge.
