For reasons best left unexplained I found myself grabbing coffee in the 7-11 today.
The whole transaction probably took a few minutes. You have to select a cup size, then a flavor of coffee, then you realize they have no skimmed milk, then you go searching for the blue fake sugar, a stirry thing, then a lid.
During this multiple choice escapade, the TV above my head repeated the title of post ... every 3 seconds.
I asked the guy at checkout if it annoyed him. "No, I tune it out" was his reply.
Your customers don't.
