Ah, sure:
1. collect money from Deimos Delivery
2. buy the items in Cybershop
3. leave Cybershop's store going south and trigger the scene at the red mist marker
4. obtain keycard from Buddies
5. go back to Cybershop... but you spawn outside the store and the automatic doors don't allow you back in
so at that point it's impossible to get the instruments in Cybershop required to complete Buddies
