A discount store about 22 years ago, part of a chain. I was 15 and worked Saturdays only.
There were prices on shelves - no prices on products and no bar codes.
There was a huge laminated book by the checkout with every product AtoZ and every price was manually entered in the till. You had to know the price by heart or search the book.
Every other staff member was full time and had worked there 5 years or more so they knew nearly all the prices. I didn't, obviously. I got flustered and panicked as a huuuggggeee queue built up because I was so slow, until one of the others came and pushed me aside to clear the queue.
I got told off, huffed at, told to learn the prices (hundreds of products). About a month in (so I'd worked there for essentially four days) I got a HUGE dressing down from a manager for my lack of knowing the prices.
So I made them up. Looked at a bar of soap and thought 'mmm probably 49p'. A pack of biscuits - I'd say about 70p. Oohhh a lovely throw - I'll call it a fiver. Some customers walked away looking bloody delighted 😂
I worked there six months doing this. No one checked on me, clearly no one balanced the till or did any stockchecks, no one cared.
They went bust a couple of years after I left, no surprise why with their 'system'!
