Today I was sitting in a hotel lounge in Dubai and a lady asked me to help send her geolocation to her friend. She asked whether she can use my Whatsapp. I said I don't have Whatsapp, but I have Messenger abd Viber. She looked at me very bewildered and asked, "You don't have Whatsapp? Why would you use Messenger?" I explained to her that in Europe we use Messenger and Viber, not Whatsapp. She thought I'm crazy. In the end I gave her hotspot and she left me to my crazy Messengering.
