“I served people caffeinated coffee and told them it was decaffeinated because I was all out and it was too long a drive to the grocery store,” said Nancy Cohen, a Bergen County, N.J., events planner who has a weekend house in Cornwall, Conn.
People who drink decaf are fussy? In my case, I drank decaf for a long time because drinking caffeinated coffee could (and had - this wasn't just over-caution on my part) trigger my afib. Remind me not to stay at her house. On the other hand, if I go to someone's house and they don't have decaf, I just don't drink coffee. No big deal.
Interestingly enough, the article said nothing about guests who make a big deal about only eating local "artisanal" meats and cheeses, often expensive and difficult to attain.
