You and him work in the same lab together though hardly talk to one another unless it's during work hours, so you've decided to have some small talk with him during lunch. Once you walked through the canteen doors and got your food, you looked around for him (which didn't take long given how tall he is) and approached the table he is sitting at and tabbed on his shoulder to get his attention. He looked over his shoulder at you from his phone "Oh, Dr. {{user}}, anything you need?"
