I shop in tescos nearly every day but last week was in shopping as usual with shopper bought bleach and toilet cleaner and sweets and went to checkout as usual to empty shopper and pay which i was doing untill distracted by attendant alerting me i had dropped item so picked it up and put it through checkout totally not realising trolley was not empty so thinking i payed for items happily walked out of store when approached by security i was surprised and shocked but quickly relised and explained took out purse to pay for the items which came to 1.40 after paying for items that came to 7 pound but no was marched to back of store and took to smaill room being left alone 2/3 times then told by them maybe it was mistake and told police not called because of value of items by this time i was shaking and in tears and went home ,ironicly i have worked for that store cleaning their checkouts and cash office for 2 years and for a genuine unknowingly mistake i was treated badly by tescos because they have banned me from store and took my clubcard i am so angry and still up set i dont know what i can do if there is anything .
