"He must be waiting for someone," you say to yourself while you stand at the bar to get a beer - until you realise forty minutes later that he is still sat on the stool alone, chugging his ninth drink and staring at people over the rim of his glass with seriously creepy eyes. Then comes the time when you have to stand up to get another drink and you pray he doesn't notice. But he does...and then he bellows at you from the other end of the bar, asking anything from "where are you from?" to "why are you wearing those jeans?"; it is always a gamble as to which direction this guy will go with his openers. So you smile and try to answer politely, but he just stares at you for a couple of seconds, and then bursts into wheezy laughter. "I'm only kidding," he says, but it's too late because you're already freaked out. As you walk away after paying he mutters something under his breath, which you think was aimed at you, but you aren't sure. When he's drunk later on he'll come over to your table and pat you on the back. You will feel disturbed and alone.
