The side-quest tip says "I should talk to someone who I know works at Garrisson's bar" (not exact quote, but close)
But I don't have the bar as visitable location, nobody works there afaik, can't call anyone on my phone (only girls are there), both baristas at the cafe only sell coffee, Sage repeats her line abot moisturizers... I'll join Discord soon.
