Enjoying shopping is one of the differences that God put in men and women. I too like to get it and get out whenever I shop. Sometimes I might spend a few minutes looking around (if I'm looking to buy a movie, video game, or picking out something), but I don't spend hours at a time.
Another thing I hate is when I grocery shop, I'll have a list of over 20 items. I can find the vast majority of those items in about ten minutes, but there'll be 2 or 3 items that I can't find. I'll spend another 30 minutes searching around the store for those last 2 or 3 items I cannot find. They just seem to elude me.
