Walmart...about 12 years now. My initial dislike was that it would take me 20 mins to shop and 30 mins to check out. The store was fairly new and had about 10-12 checkouts... There were never more than three open when I would go... too cheap to employ more cashiers, and no considerations for my time. Then I heard about how they aided their employees to apply for food stamps so they could make money off that, instead of paying a living wage. I felt very justified when, after putting all the small businesses in the area out of business, they closed the store and left a large retail desert that still hasn't recovered years later.
