We put new fake tile flooring (not linoleum, but this dense mdf/cardboard backed stuff) a store we acquired, and now every time we touch a display cabinet (metal-rimmed) we get shocked. Never used to happen when we had carpeting. One additional thing to note is that the AC was broken, and we replaced that at the same time. I'm wondering if it's a combination of a lower humidity and the new flooring that is causing us to get shocked so often we could illuminate a light bulb just by holding it. Is there anything we can do to dissipate the static charge from the floor tiles?
