Would Your Partner Have Picked it Up?

[Carouselfish]

Casual observation while at my DD's swimming lesson. Two parents watching one child swim while dealing with other 1 1/2 ish year old in the spectator area. Child drops its bottle. It rolls under barrier down onto poolside. Only way to get it is kneeling down and poking arm through gap. One parent just stares at it for 30 seconds until the other parent puts baby down and flatten self on floor to get it. Happens a second time, exactly the same a few minutes later.
I might be low tolerance at this point being FAIAP single and co-parenting, but I'd expect my partner to instinctively move to pick it up - for both of us to. Co-parent definitely would. I wouldn't put up with someone staring at it uselessly.
WWYDP do?
YABU my partner wouldn't pick it up and I'm still with them.
YANBU my partner would and anything else is irritating laziness

Disclaimer: non-moving parent may indeed have recently had a back injury or knee surgery or floor germ phobia but unable to ascertain so just going on visuals.

I’d expect the parent not holding the child to go and get the bottle. My DH would have just done it, as would I.

Though honestly I wouldn’t have two parents and a toddler watching one swimming lesson, one of us would’ve kept the toddler at home or taken it for a walk. Swimming lesson spectating is annoying enough already.
