Oh I’ve done that a bunch of times on monogamous paths, just to nudge the MC towards DIK status. Same as going to the Pink Rose, partying “without limits,” but not getting a room with Envy. It has no repercussions yet.
It may in future episodes—if your chosen LI (other than Quinn, Riona, Nicole, or Lily, obviously) finds out Quinn runs a prostitution ring and you have her number. Even though you can honestly say you’ve never sampled her cuisine, it still looks shady as hell; it’s like the wife finding out you have an Ashley Madison account “just for the lulz.”
