Wierdly, istr that both kinds of banks have different etymological roots. Not that this impacts on your question but non-cognates which are homophones and homographs are discombobulating.

They sound like they'd reverse the charges.
I mean obviously banksbod. From Wiktionary, USian apparently has 'spotter'?
Aus/NZ apparently has 'dogman' for this sort of rôle (at least as regards cranes specifically), sometimes 'dogger'. Perhaps we shouldn't try to import that one.

@sparrowsion I thought that too, although it doesn't solve for gender-neutral language. (Related to 'stevedore'?)
@chiffchaff @ajlanes

“No reversing without a person of bank”

I tried to get Banksperson used, but the old white men over-ruled me.

@sparrowsion @womump I thought spotter, like in a gym

@womump lookout is good. Pleasingly nefarious
