In the sense of honesty , I can not tell you that I "never" curse..........but, even my husband is shocked when I do.
I detest, detest, how casually some words are spoken.........
There are times when I can,shiver and allow you your anger or frustation, but a cursing mouth is not welcome at my table, in my home, or in my presence. I will ask you ( politely) to tone it down!
I will, (and have) asked the offender to leave my home. I will, as a 'manager', tell you quickly that your language is unacceptable.
I will complain to the restaraunt, theater, skating rink manager..........I will tell them, I will not come here again, if this is the accepted manner and language.
