suggest your friends not to use mobile phone

With You
Whether you're meeting a friend for a casual lunch or you’ve booked time with a work colleague, being completely present and engaged throughout the lunch is the courteous and respectful way to behave. Unfortunately, during this time of technology and easy distraction, some people will take and even make calls on their cellphone, despite the fact they're having lunch with you. Although in some circumstances, accepting a call should be allowed (for emergencies like the arrival of your organ transplant), calling friends to gossip or discuss what was on TV last night is in poor taste, as are interminable business conversations.
Although you would hope that your lunch date realizes that talking on the phone is rude during lunch with a face-to-face person, it doesn't always play out this way. Internalized excuses for phone answering during dinner dates are abundant even though they're misplaced rationales. Yet, there are a few steps you can take to let your lunch date know you mean business about enforcing some courtesy!
