Hannah Waddingham scoffed at a photog who asked her to show more leg for his pics ... telling him to watch his mouth ... albeit in way spicier terms.
Check out the clip from Sunday's Olivier Awards at London's Royal Albert Hall ... the "Ted Lasso" star looks downright horrified when the dude requests she strut her stuff and show off more skin, furiously firing back, "Oh my God, you'd never say that to a man!'
The pap mumbles something back at her, but Hannah shuts him down .
