Family Dollar complaint: Rude and unconcerned employees

When I came in I noticed there was one cashier and a line to the back of the store, but I really needed milk so I went ahead and got it from the cooler and hoped they would open another register. While I was on my way to the cooler I noticed a corner shelving unit made to suction cup in a shower so I grabbed that too and then proceeded to stand in line for 20 mins to purchase my 2 items. When I finally get up there the girl informs me that she can’t sell the shelf to me because it doesn’t have a price on it. I told her there was another one back there and the price was $4.00. So she calls another girl up there who had been sitting on a step ladder talking on her phone, to that they can’t sell it to me. So I told her that I believed there was another one back there with a price on it and was informed I could go get it myself which would mean getting back in line again all the way at the back of the store because they still only have the one register open, so I asked could the other girl not go grab the other shelf and they laughed at me and told me they don’t do the shopping for me and if I want it I have to go get it and then proceed to ridicule me to each other about how stupid it is to think they’re going to do my shopping for me. So I told them to just forget it and left. I’ve worked in retail before and I’ve never worked anywhere that I couldn’t override the system to ring something up as general merchandise if there happened to not be a barcode on it, but if this is Family Dollar’s policy then you need to change it because you’re losing money. And I’ve never worked anywhere that I felt it was appropriate to be rude and ridicule and insult the customer. I’ve also never shopped anywhere that the employees were so lazy they couldn’t go get a replacement item if there was one available. In fact I’ve never been in that situation and NOT had the employee run to get a replacement or at minimum check on the price to ring it up manually. I would suggest you need to get new employees and management at this store because their attitude is the most deplorable I’ve seen anywhere. The whole experience was humiliating and infuriating. It would’ve been different if both girls had registers open and were working hard to help the store full of customers waiting in line, but to be ridiculed by a girl that was probably pissed her personal call was interrupted is just beyond ridiculous! I won’t be back. There is a Dollar General right down the street and I’ve never had anyone be rude to me there. I just recently started going in the Family Dollar and this was my second time. And last. If your company didn’t also own Dollar Tree and all of your stores were run this way you’d go out of business.
