"Hey, can I use my Relic Shield?"
"Hey lol let me get the siege minions please"
"Any minion I attack means that we both will get the gold"
"In case you just can't tell, those hovering blue orbs around me? Relic Shield."
"Shut the @!#$ up you whiny little !@#$"
sells Relic Shield and gets ancient coin, then goes mid
Almost every game.
All to often this happens to me.
And you stop to type "PLZ LET ME USE SPOILS". Team, "what're those" [slayer-jinx-unamused]
I have switched to coin at times because of this.
Happens all the time... especially when trying for the cannon minion T.T
I've had platinum players burn abilities to take siege minions as I'm going for them. It's either they're straight up trolling or don't have a basic understanding of support items, both scenarios are really pathetic.
But muh farm 
I chose to farm champions over spoils
I have been told to stop taking CS before when I have spoils, then i have to explain to the ADC what they are.
That's why I stopped playing tanky support champions (Leona, Braum, Thresh, Blitzcrank), as the gold share/heal was a required explanation which I eventually got fed up with giving.
And so I turned to utility/healer mages instead (Nami, Janna, Bard), just to get away from that problem.
adcs should be required to at least play support secondary so they even know what half of what they put their partners through.
