This was something Shimmer took to heart, because... He was from Earth and had lived in human society since birth. "But... What if it's about to cloud-piss," she queried, before smiling and realising, "Who am I kidding? It's Nevada! It's permanent desert!"
So, off to another authentic Shimer-y delivery, she marched! OK, briskly walked, but it was done with a self-confident little spring in her step.
"Personal delivery!"
"Huh?"
"It's probably for your boss, Sir! But it's OK, I've brought my own personal escort to make extra-sure of the package's safety. He's a tower of strength, yet guaranteed to fit right in when I have to move through areas of heavy narcotics use!"
The bouncer-looking gorilla of a man at the door politely told her to wait and there was a brief exchange of communication over a hand-held radio.
"Password."
"Oh, damn it - I knew this... Uh... 'Cavity search'? No, wait... 'Pony express'!"
After that tension-filled moment, she was nodded through - Derek being given a look which was all kinds of unhealthy - and Shimmer proceeded to walk through to where she had been designated.
"Hey, we need to get to a secluded private office in the back! I must be getting a really big tip and they don't want anyone else to see!"
