Although they are amazingly annoying for the most part, they seem to help counters out through their behavior. Here's one short story:

Small joint. 2 tables open. Somehow find a spot at one of them with a freshly shuffled shoe. Middle aged man at third base having his 6th or maybe 10th beer. Starts pulling of amazing stuff like hitting Hard 20s and 18s, standing on 6s, doubling on 14 Vs 10, etc. The whole table starts getting annoyed and whispering about it. I make this a reason to stay out most of the hands as the count has dipped. The whole table gets hammered on the next 4-5 rounds. Some more amazing piece of work from third base and almost everyone leaves. The count improves somewhat. I am looking at him annoyed staying out. He loses his last chip on a hand of 9 as the dealer pulls a 6 card dealer 21 pushing the count to +2. Even the bystanders take off. I jump in and cash in on this opportunity to the fullest!
