John Mulaney gets paid by prompt fondlers to tell jokes at a party. He spends 45 minutes telling them that they are idiots, which is nice.
Basically, yeah. At my last job working in vendor support the “customer success” team was entirely sales-focused. Support (as in “my product isn’t working as expected please help”) was under a different department that would sometimes get badgered by the customer success guys if it seemed like a case was making it harder to upsell, or if the customer’s problem was that they wanted to do something their current purchase didn’t cover.
