This was just an auto insurance office before the apocalypse. One of it's employees was a former Soldier who kept his suit in his office.
Post-Apocalypse
Before the apocalypse, an unnamed man came here at some point and locked himself in the conference room after he was bit so that he wouldn't hurt anyone after he turned.
In a nearby town, Sasha writes "Dixon" on the door of an office building. Abraham eagerly takes out his knife to slay a walker down the block, but Sasha warns him against leaving evidence for the attackers to trace their whereabouts. Inside the building, Sasha situates herself in an office, as a walker pounds on the glass wall of an adjacent conference room. She asks Abraham if he wants to stand watch, or sleep. Abraham opts to stand watch.
Abraham later tells Sasha that he's eager to kill the walker in the conference room. Sasha calls him out for being reckless. "You have choices," Sasha says. "And without walkers, and bullets, and shit hittin' the fan, you're accountable for them." Abraham shrugs her off, and insists on standing watch throughout the night.
After exploring the town, Abraham brings the weapon and RPGs he found back to the office, and admits to Sasha that she was right about his recklessness. He commends her for calling him on his bullshit, and declares he would like to get to know her better.
"What makes you think I want that?" Sasha asks..
"A man can tell", Abraham replies. Sasha smiles, but says, "You have some stuff to take care of first." Abraham agrees.
Daryl eventually finds the pair and picks them up and they go back to Alexandria.
