Supermarket manager Lars Koch is offering customers a few minutes inside his cold store at the cost of €3 ($3.47), footage filmed in Friedberg on Saturday reveals. Due to the persistent heatwave which has seen temperatures hit 37 degrees Celsius (98.6 degrees Fahrenheit), the manager has decided to provide a 'cooling' service to his clients. «Customers asked several times a day so I just said... Еще we'll put a sign up and offer it. It was a bit of a joke but there's high demand,» Koch said. For the most daring clients there is also the choice of remaining in the cold store at below zero temperatures for five minutes.
