Yay, welcome Ravenfreak!
Retail (and probably waitressing) are definitely where you'd lose most of your faith in humanity, so it always makes me hapy when people show they're not always horrible like that man in your story
OK as a liquor store worker this just makes me angry. Do people not understand that that is the most expensive way you can buy it?! They put beer in sixpacks and cartons so that it becomes cheaper as you buy more! Idiots!
Unless of course it was fifty different types of beer and they were buying taste testers for all of them. In which case that's kind of cool
