Day six has two achievements to earn, but you can't earn both in one playthrough, so you'll need to rest the day to earn the second one.
I recommend doing this one second, after you have earned
and restarted the day.
You'll receive a call about a crowd outside the diner, getting rowdy because it's closed and they need their coffee!
Go to the owner's apartment next door in building 625 - apartment 7 (P. Montana)
. There's a bit of a bug problem that you need to help with. Next, go to the phone booth
outside to sort out the bug spray. They're all out, so next you'll head to the Donut store
and borrow what they have left.
When you go into the diner, select to spray everywhere. You'll go back outside and wait a moment. Then go back in - and you'll meet a giant cockroach.
After a lengthy speech you'll have two options - spray everywhere, or leave it alone. Select the option to spray everywhere to earn this achievement.
