One time I tried to say “take care” after ringing up a customer. I opened my mouth and for some reason I was unable to make a noise except for a very small “t-eh” sound initially and by the time I remembered how to make words I had to shout across the store for them to hear me. What I ended up saying was “Take over!!!” after which they glanced back at me uncomfortably and left without another word.
I am haunted by that interaction to this day.
I worked at a bilingual call centre and once tried to end a conversation by saying either “salut” or “au revoir” but I combined them into “savoir!!” So i just said “to know!!” To the customer and hung up
