A shopper was left mortified after she walked around Tesco 's with a dollop of melted almond chocolate on her bottom - making it look like she'd had an unfortunate accident.
Julie Wood, 37, shared her "embarrassing" story on Facebook along with pictures of her trousers showing them covered in lumpy chocolate.
She said she had sat on the almond and orange chocolate bar without realising and drove to Tesco by herself to do her weekly shop.
However, it wasn't until she got back to her car and felt the chocolate on her car after realising there was chocolate smeared all over her seat.
Julie, from Wishaw , Scotland said: "I feel so cringe about it all, it is so embarrassing - I had just kept thinking oh my god.
"I had gone into Lidl because they had my favourite chocolate in there and of all the ones it is the chocolate with almonds in.
"I must have just put it on my seat without realising and I dropped my husband off and went to go and do a food shop in Tesco.
"I was in the car for about 20 minutes, that meant I had been sitting on it for all of that time, and then I was walking around Tesco for quite a while.
"When I had got back to my car, I saw there was melted chocolate on my seat. I thought what was that?
"I felt my bum and I was like oh my gosh it's on my bum, it is the chocolate. But I didn't realise how bad it was until I had got home.
"Nobody looked at me in Tesco but I do remember the trolley man as I was getting towards my car.
"I remember him just giving me a look - but I just thought he was staring at me.
"But when I realised, I just kept thinking oh my god, oh my god.
"It is so embarrassing, but it is funny."
