Zero just barely lifted an eyebrow when the odd man suddenly threw himself into an entire...something. he wasn't certain what to call it other than... enthusiastic and a little loud.
His head tipped a bit, brows furrowed in mild curiosity because, once again, there was the confirmation that the guy was a little weird. Probably the type of eccentric weird that was so common around town, likely harmless.
But if he was actually annoyed about his visit to the Rock Shoppe Zero wasn't too worried; it would end up being a strange story to tell Mim later at work. And Zero found it pretty entertaining when people were strange, or at least far more energetic than he often was himself.
He was just about to ask the guy if he was okay there, what with the pausing speech and all, but settled for a lift of his eyebrows when he continued onward.
"Oh," well, objectively better than being yelled at, wasn't it? Although that probably wouldn't have fazed Zero much either. Still, it meant he wasn't terrible at his job, even if he wasn't great at staying awake during it.
"Oh yeah?" The guy could have stood to turn the volume down an octave or two, but whatever; it probably only sounded loud to Zero because he was relatively used to the quiet. "I'd ask if they were as enthusiastic about it as you are but I don't know if that's quite possible," he noted, amused.
