Then when the staff member comes along to do the final reductions down to silly prices ( like 30p for a tray of mince) she comes back to the person doing the reducing and hands the items over to be reduced further.
I work in Asda and we have a policy in our store that once you put it in your trolley, that's the final price - you cannot come back later to have it reduced further.
In our store we have two old men who come in every.single.night. and lurk at the reduced section, waiting for whichever employee has drawn the short straw and is bringing out the final reductions and if they're not out by 8:30 on the dot then they will find the nearest shop floor colleague and badger you to find out where they are. They then buy pretty much whatever is on the reduced shelf and nothing else, and won't let anyone else even get a look in, and they do this every night. It's definitely greed and not that they're skint and trying to stretch their money, because the amount of food they buy each night could easily feed about 10 people comfortably, so even if they were bulk buying and freezing stuff, they are in every night buying the same amount and must have a huge stockpile by now ... even the other "whoops" shoppers all mutter about them behind their backs!
Anyway, the greatest night I have seen at least in a long while was the night when, for some reason (probably a late/early delivery needing any spare colleagues to go help with) all of the final reductions had to be done early and the two guys weren't in yet ... well there was a lady who we all know, she's always skint but one of our nicest customers, who was just coming past the aisle as the colleague was finishing to do the reductions. This lady was always missing out on getting any of the fresh produce because these two guys would take the lot before she could even get a look in, so the colleague spotted her and went over to let her know that the final reductions were out, and led her over to the shelf ... well this woman was looking through the produce while chatting to the colleague when the two vultures suddenly rounded the corner and made a beeline over.
This woman saw them and basically just ran her arm along the shelf and dumped the whole lot into her trolley just as the two old guys got there. Well they had a huge shitfit tantrum a threenager would be proud of and tried to tell her she couldn't do that etc etc and tried to take stuff out of her trolley ... at this point the colleague stood in front of them and basically said "Now you know how everyone else feels when you come and do this, and as you know, once it's in a customer's trolley it is their item and I will not allow you to remove things from another shopper's trolley. If you try to take anything else I will have security escort you out of the store and you will be issued with a store ban" and followed through with it when they wouldn't back down. The following 6 weeks when they were banned were the most stressfree evening shifts I think I have ever worked in my store!
