I've noticed that at McDonald's in the past (though not recently). A time would start as soon as the employee starts on your order, and stops once you're given your change. The five minutes I waited getting up to the counter is ignored, as is the 1-2 minutes waiting for my order to be assembled. So I've spent 7-8 minutes waiting, and the POS machine is insulting me with the display "service time 40 seconds".
