Good selection/quality burdened by rude staffer.
The self service kiosks are handy and speed up the process. But you still may be unlucky enough to encounter Sandra the cashier who brings the customer relations skills of the IRS and the DMV to the private sector.
She was apparently attempting to one-up the mute kiosks by conducting her transactions without speaking. An outstretched hand silently demanded cash and change was returned without comment or thanks. The next poor soul in line did manage to get an utterance from her: 'Phone number!' She barked at him.
It seems the Soup Nazi act is much more humorous in fictional sitcom form.
Sandra's name tag indicated she was a trainer of other associates - a prospect that should fill both management and customers alike with dread, unless dear Sandra is held out an example of what NOT to do.
