@HYBRID_BEING There's a great difference between a place being "not that good" and it "outright sucking". The responsibility here lies in forcing your suggestions ("Hey let's go to this place, trust me, you guys will absolutely love it!") rather than passing your suggestion ("Hey, I hear of this one pizza place that serve great cheese, so you two who are hungry and you who adores cheese should like it"). The first one pretty much leaves you with all the responsibility since you kinda forced it on them, while the other one makes it a shared thing due to the other people also vouching for it due to their conditions (hungry and cheese lover).
Also, one thing to consider is the hype and the outcome. When you promote a place, you naturally generate expectations for it, so if the food comes out differently from what your companions expect, you will generate backlash in accordance to the hype you generated and how bad the food was; the thing about the pizza was that, while it was "not that good", it didn't suck (it was a "meh" pizza; not good, not bad, but meh), so the backlash was mitigated, not to mention that this was a "since we're hungry" suggestion and not a "it's a great place" suggestion, so the hype was lessened (besides, people say that hunger is the best condiment).
So, collective responsibility, smaller hype and lessened backlash, combined with greater social experience pretty much made the "bad outcome" go under the radar. It's a social thing, but then again that's what this series is about.
