Someone called it a phone when he arrived, and that's stuck in Loki's brain now. (Also the concept of a tablet is still quite space-age to him.)

"...You are a fucking genius, man."

Loki practically falls over a bar stool when he finally gets there, as his eyes are glued to his tablet and he's paying zero attention to where he's going, except for occasionally checking the map display for that red dot. "Shit! Oh, hey. Free booze guy!"
