Is it me or do people have no respect anymore?

So lately I got a new job at the Get N Go Shell Gas Station well today at work some guy comes in and buys a pack of cigarettes and a 32 case of beer. After I gave him his change and everything, I went to restock some of the cigarettes and I looked and realized the beer was still there so i thought the guy went to the restroom, seriously the pack is pretty big shouldn't be that hard to remember. well a few minutes later I see the guy drive off. I tell my manager that he forgot his beer, and she tells me to put it in the freezer in case he comes back. A few minutes later he comes back and I politely tell the guy his beer is in the freezer. He starts yelling at me and calling me a prick. He grabs his beer and talks to my manager out front. She taps on the window giving me the notion to come outside. She said the guy said "That little sh** in there didn't remind me to take my beer" "I was sitting in my car packing my cigarettes and that bastard didn't bring my beer out." She told me she told him it wasn't my fault that he forgot his beer. The thing I find funny is that he remembers his small pack of cigarettes but forgets his case of beer thats bigger then his head. Like seriously all that for a case of beer. I found that guys attitude very uncalled for Any interesting stories from your places of work?
