Women are meant to be the experts at shopping, but new research reveals the whole experience leaves them stressed. The surprise findings show that not all women get comfort from shopping. In fact, in a supermarket environment, one third of females feel it a burden when they do the weekly shop despite being organized and armed with shopping lists, The reason why women are more nervous in the supermarket is largely that they are rushing round trying to conduct the shopping as quickly as possible. Doing the food shop will be one item on a massive list of jobs，and something which simply has to be done at speed. Women even admitted to having an argument with another shopper in the supermarket－either because of trolley rage, fighting over the same item or queue jumping. They can't stand feeling rushed when the cashier scans items too quickly so they struggle to get everything into the right bags. In contrast, three quarters of men quite enjoy their food shopping experience and are happy to push their way around the aisles searching out products. Men are less forgetful about what they want to buy, are less likely to feel rushed by the cashiers and are more methodical at the checkouts. Men seem to adopt a much more laid back and methodical approach, taking their time looking for bargains and make sure they're getting the most for their money. But the poll suggests women are the savvier shoppers—as they are less baffled by all the different brands in the shop and are more likely to ask for help if needed.
