I rang my local ASDA (a supermarket for any of our European friends that aren't aware) to find out their opening times.
This is what I heard - seriously....

"Thank you for calling ASDA Darlington. We are open 24 hours. Our opening times are 8am to 10pm Monday to Saturday and 10am to 4pm Sundays".

OMFG where do they find these people?

consider it as a 24, it's just you've to break a window when the door is closed
then if you get caught just say it's a 24hours
