Long lines or long walks? I like walking the lines don't bother me either.
Once or twice a month I don't mind a long line specially if I see other products that are not on my list and discover new things. As I posted before in this thread even though I buy a few things online I'll never give up the experience of going to the supermarket. We can always find an hour twice or once a month to do it. I find grocery shopping a relaxing experience and for some of my friends who live in a suburb that might be the longest walk they do.
