аптека улица фонарь
well you can't just offer sweets to random people on the street: there might be builtin mistrust, fear of being manipulated and hurt.
also, everyone's needs are different and change over time. don't ever hope what you need right now is somehow representative of what someone else needs. first of all, make a deliberate effort to reach understanding. put in the hours, make mistakes and learn how to communicate.
this will certainly be harder the more social distance there is. not only your perception might deceive you; depending on your view in other party's eyes, they also might hear a distorted version of what you're saying! that's your job to compensate for that - learn their language.
