Yes coffee is reliable and I'll go mint-chip for nostalgia's sake once in a while. My childhood best friend's favorite. I am loyal to Thrifty's and will try a different flavor if it sparks my interest. The line on a hot day is something else, and the customer age range is toddler to geriatric with the walker. How the adjacent Baskin Robbins 31 Flavors stays in business I do not know.
