One of the challenges in Fortnite Chapter 2 Season 7 Week 1 is to collect a task from the payphone. Payphones are a new addition to the map this season and, like NPCs, players can communicate with them and get tasks. Upon completion, tasks will be rewarded with gold players, which they can use during the games to use various services around the map.
Although you can find payphones all over the map, we can show you the exact location of the one we used to wrap up this task. Head to Pleasant Park and you will find that a payphone has been added to the bus stop on the south side of town, and you enter the area on the road.
In interaction with the payphone, you get a selection of tasks to choose from. Make sure you select something that is easy enough to complete, such as being knocked out using a weapon you have already collected. Then just complete the requirements of the task you choose and the challenge will be complete.
You should always be careful, because on the payphone you will be quite exposed, so you do not spend too long weighing your options, or another player will probably use it to distract you and use you to complete your own task.
