My first recommendation was that you try different shoes. I'd still try this, but if this is happening to everyone, I'd suspect the floor tiles. Some materials are more likely to generate triboelectric charge exchange.

We tend to think of "ground" as an absolute thing, but it's not, it's relative.

This has me wondering if that store has some sort of ion generator, intended or accidental, that's pumping out ions into the air. If that were the case, you might charge up faster than your cart if the cart wheels were more conductive than the soles of your shoes, or vice-versa.
