One of these had a sign hung behind the counter informing all that this was the store of "two wonders". First you wonder if we have it, then we wonder if we can find it.
Another shop of that era sold antiques. Its sign proclaimed it was the shop of the three "don'ts". Don't bring in your children, don't bring in your dog and don't tell us your grandmother threw this thing out. I don't know if many years into the future people will have any fond memories of the current crop of home centers.
