The other day I had a crazy notion that I should build up my caffeine tolerance to avoid Italian stink eye asking for decaf in Florence. So I ordered a slightly caffeinated bevvie and after drinking just half of the half/caf I realized I am a total wuss. I had to eat a couple of tums and I felt like I was coming down from a bad acid trip. Hopefully when I get there I can find a cafe that will cater to my intolerance of their staple substance!
