Jus’ watching A Hole In The Forehead and there’s a lady-whipping scene in this as well.
One of those three gals from the Sonoran bar scene gets flogged - both to the gunrunner fellah in leiu of some rifles - and with a whip.
Luckily, it is highly important to the script and not at all gratuitous.
Blimey - y’go 5 years without a whipping and 2 come along at once. :o
I’m watching One After Another, literally having jus’ seen AHITF, and although we dont get the poor gal lashed for us all to see in this, Jose Manuel Martin (who makes a much better bandit chief than Hundar in AHITF - and therefore is more deserving of the Hall of Fame accolade, Brother Lone Gringo 
) has whipped the unfaithful mexi-chica and we can see the lash-gashes and blood.
This is however, completely necessary to the plot, as it is the festering hatred that she now harbours that adds to the twisty-turny story that is unfolding.
Anyway, to have a break from my Spagvember double-header, I shall be going for a short walk :
and return having been ‘on the lash’ myself for the finale of this goodie!
