"Is this your phone ringing? Probably, it’s mine. "Wait a second, please, I'll answer the message...". Perhaps you don’t even ask to wait, but just take away your gaze from a person on the phone and start writing a text.
Do you want to stand out from the crowd? Do you want to be the darling of the people, because of importance that they give to the interlocutors?
Stop checking your phone constantly.
