An issue with The Secret Recipe (quest)

[Fortress]

Alright so I'm doing this quest called "The Secret Recipe". It's about finding all CyCorp's soda recipes in the CyCorp Corporate Offices. It keeps saying that I need to get all the soda machines in the level but what does that mean? I keep shooting the soda machines but I don't know if it helps or not. In the Quests tab it says I need to collect 4... are the recipes in chests or something? Please help as I am highly confused.

enter the room, the vending machine is that thing on the left at the first corner of the map, try tapping it instead of shooting it

You need to open the 4 "safes" or one safe 4 times if you'd like, there is one in the room with the Squad Leader and the supply crate that holds the security halls key:
