It's not my fault you couldn't read the receipt....
This just happened about 3 hours ago
At least 3 hours into my shift I start serving a customer (let's call her <PERSON>). In my store we can type a number, press multiply and scan one item through so it comes through as whatever number is typed (i.e if a customer wants 4 cans of beans, I would type '4x' then scan one of the cans through) and this is shown above the item I have scanned (e.g each can is 89p it would read '4 @ 89p'). This is important to the story.
<PERSON> has a decent amount of items so a couple times I used the multiply method. <PERSON> pays and walks away from the register so I start serving the next customer.
As they leave, <PERSON> cuts in and looks mad.
<PERSON>: you've charged me for 3 of these vinegars when I only bought 2.
Me: can I take a look at your receipt?
(<PERSON> shows me the receipt and points to '2 @ 99p' for the oven cleaner which is below this. I point this out to her)
<PERSON>: you're wrong. 468
You've charged me for 3 and overcharged me. They were 49p not 99p!
Me: ma'am the 2 thing isn't for the vinegar it's for the oven cleaner. See?
At this point <PERSON> keeps telling me I'm in the wrong. I also have a queue of customers lining up, a couple of them looking very baffled at <PERSON>.
<PERSON> then proceeds to blame me for her mistake. I gave her the right answer and she didn't like it.
Me: would you like me to call a manager?
<PERSON>: yes please
I then call a manager but at that point <PERSON>'s gone.
She had also told me apparently "this" was the reason her son left the store. I've never seen this woman in my life and I honestly doubt her son left here...
TL/DR: <PERSON> needs to listen and check receipts 329
