Appels

There are all these stands around that say Appels 50. When I say “all these” I mean hundreds…all over! The first day I saw them I thought they were fresh apple stands. Actually Appels in French is call. What they are selling are phone calls. You can go and use their cell phone and call someone. They have this as there are not phone lines to most of their phones. But I am not sure who they are calling as most people use these Appels to call…are they just calling other Appels?
