Stop in for a cup of coffee

True story. Coffee is so strong here, you dare not drink before breakfast. One time, years ago, I did just that. Two glasses of iced coffee. Had a racing pulse and heart murmurs for an hour. Learned my lesson.....
Kind of like getting coffee from a machine in Italy. I put the coin in, cup dropped, coffee came out, and I thought I got cheated. One gulp and it was gone. The Army guy stationed there tried to stop me...too late. Same thing racing heart felt like crap for hours.
