I like to pick my own produce and check dates so online shopping's not for me but I avoid the crowds by shopping early in the morning.
Seriously though... people are mean where you all live.. where I am we let folk go ahead of us if we have a huge cart full and they only have a few items!
I used to do online shopping almost exclusively, but that was only because of my weight-related mobility problems and the fact we were up a few flights of stairs.
Now I've lost weight (just over 9 stone so far!
) and am feeling better and moving about so much better, I actually go into the supermarket now, and it is great to be able to check dates and stuff. But I still use the self-service tills because I just want to get in and out, and don't really want to make small-talk with the checkout people.
