Dubious that I could haul 32 lbs of peat moss on my bike?!

Went to the garden shop to buy some peat moss. Since I was there, figured I'd go all out and buy the big one. I pulled up on my bike at the pick up area and the service guy looks at me, turns around,, walks back in, comes back, out, gawks.

WHAT?! Lemme guess, never seen someone haul on a bike. Or is it that I'm a chick?! Both?! He still has his mouth hanging open. I ask him how he is with my best smirk.

"Dubious," he answers with a head shake. "It's heavy, you know?!"

I tell him I know, hoping he catches the annoyance in my voice.

I make sure I grin extra cockily as I roll out. He must not know who I am.
