Once you make that decision, the entire aircraft needs to be deiced. You could argue that the tail didn't need deicing, but that Captain was most likely exercising his authority to make the most conservative decision. I had a buddy that this happened to in Denver on a blue sky day with the temperature in the 40s as well.
The MD-80 had this problem until they put the upper wing heater blankets on the airplanes.

The MD80 issue was usually solved by running outside to the fuel panel right when you blocked and getting the cold wing fuel transferred into the center tank before the fueler showed up. A PITA...or you could just deice.
Also, even in this situation, if an airplane needs deicing, one is best served by letting the deicer decide what to spray. Limiting the surfaces that they can deice puts needless liability squarely on you.

I nominate the lone airline crew deicing both wings AND tail on the ramp in Vegas the other morning. With not a cloud in the sky and an OAT of 48F. 🤔🤨

He may have a point after all.
I’ve never seen wing ice in Las Vegas or any climate that wasn’t humid. If it was raining that day maybe. Unsure what the weather was.
Even so unless SOPs forced me to I wouldn’t deice the tail too.
So it could be a crew that did the wrong thing or the right thing. Not enough info to blame either party IMO.

They *might* have had frost from the night before. Or dew that looked like frost (if it's a NB or bigger I'm not going to get a ladder and crawl around the top of the wing doing a tactile check). Keep in mind that a cell-phone pic of something that looks like frost could generate media interest and an annoying company/FAA investigation... got to respect the optics these days.
Or they might have been padding their block time, that's an old trick if the company is screwing over labor. Or they might have been just trying to stick it to the man (de-ice ain't cheap... ).
