You've probably never had one of those times where you text "I'm ready!" and your ride says they will be there in just a couple of minutes. Then 5 minutes later "Where are you?" "Oh, just around the corner, be there in two minutes." And on and on, and when you at one point text or call "Should I just go back inside and wait?" the answer is "Nope, I will be right there and I don't want to have to wait for you." And an hour late your ride finally shows up, and if you went back in to wait in comfort you get an angry "Where the hell are you? I'm going to leave if you don't get out here right now." And you can't respond in kind because you really will be left.
