There should be a pinning system or any system that prevents the user to block (for a day or an hours) the one who he is suppose to meet on the app to avoid any inconvenience to the person who is willing to go to his place then blocks when he is near.

Once the user decided to meet up with this person he has to pin the person and once pinned he cannot block it and removed his location (temporarily for a day or an hours) to show that he is serious to meet up. WASTE OF TIME
