The team was not careful enough to cover items that could had been affected/damage by the chemicals, therefore some merchandise from the store had to be toss away, few food and paper goods. The team should be more careful with that, and better detail cleaning at the end. We had to disinfect the area due to left over residue of the chemicals. The team also left garbage outside the store, which could have been resulted on a ticket to us. They need to be more careful.
