As long as it's a separate building from your home, can you just imagine the stuff that'd be inside some people's vacuum's? I use to own a small neighborhood video store, you'd really have to watch close for what came back with those movies. One time I didn't even have to look that closely as this big huge cockroach was running around inside, you couldn't miss it....lol. Thank goodness it was before bedbugs became a thing again.
