As someone who works for Walmart... Doesn't look like it. The sales tags you can see in the background aren't the kind Walmart uses. Looks more like a Kroger or Kroger-owned store.
That being said... The assumption is completely understandable, and I would not be surprised to find something like this during my shift.
I was gonna ask - PeopleOfWalmart? I can see it now - a 400lb man in fur suit bikini, engulfing the electric scooter, half-eaten peach in one hand, half-empty Fireball nip in the other, freshly knocked-over produce display spread in front of him.
