When entering the check-in staff is busy. Nobody accepts customers, we walk around many buildings. Asking anyone, no one knows So try calling the number provided, when someone answers the call, we tell you to check in. Finished, he cut the call without saying anything And let another friend call, when informing that they will come to check in, they cut the line as before We don't know if he hurry or what. But doing this makes us feel uncomfortable as much as possible. Please leave it.
