US clothing retailer Gap has been targeted by protestors in London who accuse it of ripping off British customers by charging them higher prices for paying in pounds and refusing to let them pay in euros. Like many retailers in the UK, Gap displays prices in both pounds and euros, with the price conversion leaving the pound price the more expensive of the two. However, Gap will not accept the European single currency in its UK stores because Britain has not joined the euro - meaning that Britons are charged more for the same merchandise than other Europeans.
