I wouldn't expect a coffee shop to do the decaffeination there. Rather, the company that does the decaffeination is its own thing, which then ships their product to the roaster, which then ships their product to your local coffee shop.

Also, if you're buying fancy coffee, chances are it's Swiss water process, for better or worse.

Worse? You mean in comparison to the CO2 one, which I hadn't heard of before?

My understanding of the consensus is that it favors EA decaf.
