A woman has slammed Tesco for 'humiliating' her in store, claiming a staff member confronted her for wearing a bikini top and even told her to "grow up".
The anonymous woman had gone shopping at the Driffield store in East Yorkshire yesterday - which was the third hottest UK day on record.
But despite doing her whole shop with no problems, the woman claimed she was stopped at the till by a female assistant who asked her to refrain from wearing a bikini next time she came in.
A 'heated' row broke out at the tills and Tesco have since apologised to the woman, claiming they have reminded their staff to be courteous to customers at all times, Hull Live reports.
The woman said: "I've never felt so humiliated and discriminated in front of everyone just for wearing a bikini top and by a staff member.
"The staff member came to me when we was at self scan, she'd already let me walk around the whole shop then came to me in front of everyone, people left right and centre, and said, 'next time can you wear a t-shirt, even men aren't allowed in without their t-shirts it's the policy'.
"A bit of a heated argument happened and she ended up telling me to grow up and said 'good' that she'd lost me as a customer, well that didn't help the situation whatsoever.
Noticing the scene, another younger employee came to intervene and tried to comforted the upset customer, giving her "a cuddle" and got the store manager.
The woman said: "He came outside and apologised repetitively for how she went about it the complete wrong way.
"I explained how it's not normal for me to wear a top this like but it's 35+ degrees, I don't just carry t-shirts around with me.
"I even explained how many of other women/girls were going in with some of their cleavage showing and very tiny belly tops with no bras on!
"But somehow I was the only exception?"
"He said he understood it's not normal weather and even schools and train services have changed their rules to accommodate this weather and said he'd have a meeting with her."
Tesco has now apologised to the woman and claimed it had reminded staff to be considerate.
A company spokeswoman said: "We’re sorry for the way this was handled, have apologised to the customer involved and reminded colleagues in store to be courteous to our customers at all times."
But the woman claimed Tesco had 'lost' her as a customer as she finished: "I'm just so fuming and upset, it takes a lot of courage to wear something like that, I expect words off 'street chavs' but not from a staff member where we regularly shop.
"What if she worked abroad or even in Brid? Everyone's in bikinis in Brid."
Some schools and employers have relaxed their uniform policy on account of the extreme hot weather which is forecast to last until Tuesday (July 19).
Weather experts suggest today could be the hottest day ever recorded in Britain if the mercury reaches predictions of 41C highs.
