The second wave of Safeway hypermarkets will have more warehouse space at the back and a slightly different hub concept, revealed business development director Steve Webb. The company recently blamed disruption at four large stores being converted to the new format for a lacklustre set of fourth quarter trading figures, as bosses continued to tinker with the hypermarket concept. "It was a new departure for us dealing with such high volumes at Plymstock," said Webb. "So we've had to do some work on the backroom. We've also changed the hub and some of the non food space allocation. But it's tweaking, not radical change." The company's second hypermarket after Plymstock will open in Glasgow on May 15, with a further three in Nottingham, Northampton and Milton Keynes to follow in mid June, three months behind schedule. {{NEWS }}
