DD is first year at uni in house with 4 other girls (private rental not halls). They are isolating as have all tested positive. They have arranged an asda grocery delivery tomorrow and have put in the notes section that the household is covid positive as they are worried for the delivery person. Does anyone know how the delivery will take place ie will the driver ring the bell and then step back 2 meters.....should DD maybe not open the door, but instead talk through a window to them? They are feeling bad to out a delivery person in this position, but really need the supplies. Is there any more they should do ie phone asda in advance?
