If you've ever worked in a supermarket or a similar retail job, then you'll know that there are often tricks of the trade that you get told to do every day that most customers have no idea about.
One former Tesco employee has said there was one rule they had to follow when they were working on the checkouts, and while it was supposed to make shoppers feel more welcome, it often backfired.
The former supermarket worker posted a video to TikTok in which they said their manager told them they should always strike up a conversation with customers when scanning their shopping, as you never know how much difference that one chat could make to a person's day.
