Heavy shop for Ms.N

I went over to Ms.N's place earlier as I had an hour free prior and after we agreed over the phone that I can come early.

She was happy to have me over, I collected £20 and her shopping list. We went through it to ensure that I understood what she wanted.

I ran over to Tesco's in Catford to get all the items, but I realised as I was filling the shopping basket that it was going to be a heavy shop. It was and thus, I took the bus over to her place. She appreciated what I did, but I got fresh milk instead of long life....which wasn't mentioned in her shopping list. Still, she was pleased and said it wasn't a massive issue.
