Cheap grocery store with a REALLY strong fish market smell.
The last time I was in some disgusting toddler was walking around touching herself (no pants or diaper) and touching the fruit. I personally would have banned the family, because that's not only unsanitary but it puts other customers off. Whatever the disgusting family could spend would never make up for the lost sales from the rest of us. The "No shirt, no shoes, NO PANTS, no service" sign needs enforcing, regardless of age. Gross.
There's also open bins of freshly cooked food. I'd love to try those samosas ("curry pastry") that look so good, but as long as they're sitting on a shelf with no tongs and no sneeze guard I'm not willing to. Ignoring the potential for that kid to have touched them, eww. Do NOT eat anything without cooking or washing it really well!
I'm also not a huge fan of the hanging dead ducks. Gross, but sort of fits with the disgusting fish market smell.
Imagine a downtown Walmart, remove the bright lights, working conveyor belts and sanitation and you've got Centra.
