I just dealt with a member who returned a washer and dryer the same day it was bought for no other reason than they found mice p--p right on top of the dryer when they unboxed it. All of the washer and dryer boxes have little rectangular holes on top.
I had lunch in the breakroom the other day and heard some scurrying in the ceiling. Others have said the same thing. The store manager keeps saying that it is the HVAC. That was around the same time somebody from softlines swore up and down they saw mice running around in their stockroom. None of the managers believed her but the mouse p--p and the angry member who bought and returned the washer and dryer will confirm it.
Maybe they don't want to believe it for fear of this becoming an unexpected expense. An extermination bill for a large store is easily a couple thousand I suppose.
