I live near a "large retail computer store". Set up like a Barnes and Noble store, only selling computers, there is a coffee bar setup for customers waiting on repairs and consulting.
The increments are 4, 6, 8 and 10 BUT the larger the size, using the same K-Cup, the weaker the coffee is, unless you use 2 K-Cups or more to make one cup which can be very costly. Anyway my choice of coffee was 8 ounces which resulted in a extremely weak cup of tasteless brown water; something a passing car would spray after a rain. I report, you decide.
