/form Aldi has told shoppers to keep their tops on after the sweltering heatwave sent the number of semi-naked customers soaring. . People have raised fears that some of the topless men and scantily clad women could affect food safety due to them being visibly sweaty. The discount retailer displayed a notice at the doorway requesting that patrons cover up when shopping in store, reports the Daily Post . It reads: “For hygiene reasons, we respectfully request that all customers keep their shirts on whilst in the store during the hot weather. “Thank you for your co-operation and enjoy the sun!” One Aldi shopper agreed with the decision saying: “I can see why they have done it. "At the end of the day I don’t want people sweating all over the food I am picking up.” Another said: “It’s off-putting. It could put you off your tea!” One male shopper said: “I wouldn’t do it, not in a food place anyway.” Enforced dress codes are not a new phenomena in UK supermarkets. Two years ago Tesco made a similar decision to ban customers from wearing pyjamas or coming in bare feet in a branch in Cardiff. At the time a spokesman said: "This is to avoid causing offence or embarrassment to others." And back in 2013 a Tesco in Tiverton, Devon banned scantily clad women and shirtless men because their bellies were branded a health and safety risk. The dress code was imposed after complaints about “half naked” men and women stocking up on alcohol and barbecue goods. Bosses at the shop said bare torsos could pose a health risk as they could drip sweat on food. People with no shoes have also been banned – with the dress code displayed in the shop’s window.
