After we'd teed off the next hole I'd mention it whilst we're walking to our balls.
"I think you flicked the sand back there. That should be a penalty, just so you don't get stung by someone if you've got a good score going another time"
I kinda agree but I'd never cop out and call it being stung by someone. That implies the person pointing out the penalty is doing it out of spite.
