Rant mode:
As someone who currently works in the photo department at National Pharmacy, I have a corollary to this: customers who come up to the self-serve kiosks and literally dump their stuff on the counter and expect you to do everything for them.
They're called self-serve kiosks for a reason. I can understand that you might not be technically inclined and need help--sometimes a lot of help, our kiosks are confusing and there's not a bewildering amount of products we can make for you in-store--but it's the (usually older) people who just throw their hands up and say "Do this for me, I hate computers!" that really get my blood pressure rising.
Want to know the cost of something? Actually read the prompts on the screen; every possible item we can make or have made for you also includes its price. Want to know the size of something? Move your eyes up to look at the huge display behind my counter which has mugs, t-shirts, wood panels, and every size of poster we can make in the store! It's not that hard.
We're not commissioned salespeople, so I gain nothing from giving them heaps of attention. In fact, it's quite the opposite: corporate wants everyone to spend as little time as possible in the photo lab, so it's heavily automated--once a customer submits an order we're just supposed to push the "print" button and walk away until it's done, which we obviously can't do with things that require complex assembly like canvas posters, wall calendars, wood prints, sets of greeting cards, and etc. Not coincidentally, these are all things that are flying off the shelves this time of year. Hell, I've heard National Pharmacy is eliminating my position and simply downgrading everyone who isn't a shift lead or SM/ASM to the wonderfully generic rank of "Associate" next year.
To compound all this, there's not a day that goes by when one's in the photo lab that you don't have a huge list of things to do around the store. Being that National Pharmacy wants to make as much money as possible by running its stores on as few labor hours as is humanly possible, people in Photo are not just machine operators but also store stockers, replenishers, cleaners, remodelers, and general "gofer" people who have to cover the breaks and lunches of the people on front register and help them out with long lines, price and stock checks, and also basically handle any general 'customer service' calls that come through our phones. I often just don't have the time to deal with customers who need their hands held for two hours, not when I've got a daily list of tasks to do a mile long.
