Buy a cup of coffee from a machine.. anytime over the last 35 yeaars... that paper cup MAY hold 6 oz, overflowing...
Styro coffeecups hold 7 oz, but if you put more than 5.5 in, youll spill...
When I was working at Mr. Coffee, and designed the "personal iced tea pot" w/patent, I had every coffeemaker in the world, sitting in front of me.. and yeah, a cup in coffee terms is 6 oz.
I had the best coffee beans in the world at my beck and call, I could re-roast anything I wanted, I could brew what I wanted... all because, they simply had it there.. I gotta say, I developed a quick coffee addiction, but luckily right next door was a place called the "Winking Lizard", a bar I started doing beer tours in
I could call over, order my lunch, walk there and have lunch, and 3 beers on my "list", and repeat after work... did a record tour of 68 iirc, beers, in 20 days, but total elapsed time was 23 hours.... I have 6 different tour jackets from them.... 6 tours, 6 jackets, about $1000... coffe is good..
Like I say, thank Mr. Coffee.. he redifinedthe cup.... not the Eurotrash, Mr. Coffee....
