Uses of Latin: airport bathroom encounters

My flight had been rerouted and canceled, again. I ran into the old woman in the bathroom, the lady who had been on my previous flight, and she exclaimed, "God willing we get through to Dallas!" with which I reponded "Yes, Deo Volente indeed!" 

A mother and her teenage daughter from Pinterest summer world gave my disheveled traveler appearance a look of disapproval as they skipped washing their hands to fix their hair. 

I again nodded a smile to the elderly woman and proceeded to wash my hands for an extra five seconds to rub it in -- the soap I mean, of course.
