Hyphenate THIS (picture me flipping you off)

Today me and miss thang went to the Probate Office to get the Marriage License...
(Why do they have Marriage Licenses and Gun Permits in the same office??? Foreshadowing???)
I get the clipboard and start filling it in for both of us, full names, place of birth, parents names and places of birth, etc. When I got to Designated Sirname I filled in the Fiance's box with my last name. She said - what is that? I didn't really know so I said we would ask. We get up to the counter and ask. This is where I am shocked to hear - what if I want to hyphenate???

Did she just say hyphenate? Who is this person standing next to me?
I blush, immediately start sweating, 15 people are overhearing us, and I politely say- WHAT?

This came as a total surprise to me. Luckily the clerk berrated the girl into submission so she can't blame it on me. Talk about bullshit.

I deserve to be angry about this - in actuality I think it is funny she got beaten down by the clerk but wonder what this means going forward. I guess I am the one the truely wants to get married. Who'da thought that.?.

I guess I shoulda realized something was up when she comes home from the bridal shower and says - I got this and I got this, and this person gave ME this and that.... Whoa nelly... I correct her by saying "Don't you mean WE received this and this person gave US that.???"

I swear - if I die under curious circumstances - you know the #1 suspect... HA... That's funny.
