A lawyer has issued a warning about supermarket self checkouts saying she never uses them.
Lindsey Granados highlighted the risks of using them in a TikTok video which has since gone viral.
The criminal defence attorney said she has dealt with "countless" clients who have been charged with theft after the self checkout machines did not scan a product properly.

She says shoppers at a large retail store in the US have been charged with theft, even when they did not mean to steal anything.
The lawyer explained how sometimes the machine do not pick up items meaning some of her clients are charged with the misdemeanour, the Sun reported.
Lindsey said in the video: "Those machines are faulty in a lot of ways and they are not particularity sensitive and they will unfortunately not scan items from time to time.
"I can't tell you how many clients I've talked with that have been charged with larceny (theft), because one of those machines didn't scan appropriately.
“Why would you steal with someone else's money who's paying for it?"
Another lawyer said they were talking to at least two or three people every week to have experienced the issue, Mirror UK reports.
Last month it was reported some supermarkets are set to introduce advanced self-service technology in a bid to cut down on shoplifting.
Stats show a third of shoppers are estimated to fail to pay for all their items when using the unmanned tills - though not always intentionally.
Experts say the industry has been forced to consider advanced tech to crack down on 'swipers' who are pinching millions of euros worth of items a year.
The new systems can detect when an item in the bagging area is different to the one scanned, as well as spot other suspicious patterns.
Professor Adrian Beck, of the University of Leicester, liaises with stores to help them spot the tricks that some shoppers pull and has surveyed three thousand people on the changes.
