We can only acknowledge you over here.
At the CVS at Farragut North three cashiers stood idly waiting to serve someone in the line. Five feet to the right I stood at the photo counter awaiting assistance. The inevitable resolution was that I need to go walk through the cashier line to get a clerk to walk back over to the photo counter to get my pictures. Protocol and structure are important in a business, but so too is knowing when to deviate to improve the customer experience.
