At a competing chain to "Mart of Wal" (love that by the way!), we have one greeter who just annoys the living crud out of me. He goes out of his way to be cheerful (which is of course, probably why the company hired him), but every.single.thing. said to him sets him off in peals of laughter that could be heard throughout the very large store. (Think maniacal circus clown in a horror movie laughter.) I think someone could say, "my dog just died and my mother is about to," and he'd still give the maniacal laughter. Plus, he tries to get into a conversation with every one who comes in. A full blown conversation.
The local paper did an article about him and apparently he's had a lot go wrong in his life and this job is his way of staying positive. Okay. Fine. Touching story. I get it. Really I do. But, Mister, I just want to go in, get my items and go. Please, go bug someone else.
