I've learned to not question what the customer wants. If I push back and think "you probably really want solution X over the solution Y you're asking for" more often than not it turns into a big fiasco. Every issue that comes up becomes my fault for suggesting X and not going with Y. Where as if I just do Y as they asked then they associate the issues with Y and not me.
