When I worked in retail, I worked in many departments. I worked in Jewelry, Cosmetics, Stationary, Small Appliances, Bakery, Ice Cream shop, Health and Beauty Care, and then also spent a good portion of the time around various departments of the store, doing resets, stocking, and generating reports. I am not saying it is ok to be wasteful, but unless the store has a policy on it, there is no reason for her to pay for something she couldn't eat. From my time there, there were so many times that food had to be thrown away for one reason or another. There was often discrepancies in inventory where items just weren't there and we had to fix the error. There were items that didn't sell but were there so long they basically "fell out" of the computer system, we got no credit for it and had to either throw them away or try to get some money for it. For example, we had a cart of candy bars sitting in our backroom for six months that had fallen out of the system, they had 25 cent store generated scan codes on them, but there was no place to put them on the sales floor. Bakery goods that were "expired" thrown away. In the ice cream shop, we had to take the large tubs of ice cream out and let them sit for about 10 minutes or so to soften enough where we could scoop them, so many times someone including me, would forget and leave them out overnight, then someone would come in the morning and have to clean it up, stuff happens. Arashi expected a certain product and it wasn't the product she asked for, it may not have been their fault but it wasn't hers either.
Arashi could have probably found something else, but she needed time to process what was happening, but was verbally attacked before she had the opportunity. There were times when I ordered something that wasn't what i thought it was, so i would decide is it my fault or not, if it was my fault I would pay for it. Also, when you don't have alot of money you can't be paying for something that you can't use, even if the item was a luxury to begin with.
I guess I have been in Arashi's situation before, and I know how it feels, so I feel like I got to fight for her even if I can't do anything about it.
