Can I get some month-old truffles?
One of the biggest hassles of working in a candy shop is replacing the display items. This is why employees would much rather pull something out of the back than get something from the case and replacing it later on. However, if you insist, they’ll more than likely take the stuff from the display case and bag it up for you.
But you should never insist on this. Those items might have been there for months on end, and it’s not unreasonable to think that there could be mold in or around the item. Just follow what the employee does and wait for them to get your stuff out of the backroom storage.
