Straddling before the cards are dealt

[Captain R]

Bay101 20/40:

SB posts, BB posts her blind and says "we chop, we chop!" because Bay101 only drops $1 if folded to the blinds and they chop (instead of the normal $5 drop).

I jokingly stick out a live straddle when she says this and then take it back before the dealer deals the cards.

As I take it back, another player says it has to stay because it was my action (even though the cards haven't been dealt).

Floorman is called over and he says I technically have to leave it out, but he lets me take it back because 8/9 players agree I was only joking. It's not clear to me if he understands that I took the chips back before the cards are dealt.

Did floorman make the right call? Do I technically have to leave the live straddle out?
