I worked at Walmart for like 9 months back when I was in college. They suck so bad. They actually tried to fire me for shoplifting, even though I never did anything of the sort.
Remember back in the day when Walmart used to sell fish? I worked in the pet department, dealing with the aquariums and stuff. One day, one of the pipes cracked and there was water everywhere. I ran to the garden department and grabbed a few PVC pipe fittings and a piece of pipe. I fixed the leak and told one of the managers. The manager said that since I took the stuff without asking first, it was considered theft, and that he had to let me go. I replied, "That's fucking retarded, I quit." On my way out, I undid my repair, flooding the area.
