Memo: Janitor

Ugh. I'll admit my mistake. Sorry for walking into the wrong area. I'll update my access card promptly next time.

I'm not going to excuse myself again by saying I was only recently assigned to this post. I know the Test Site has many floors above and below ground, and that every floor is clearly marked. I'll pay attention to the signs next time.

Yeah, I know. Some areas ain't safe. Barging in without protection might get me killed. Got it.
