Timberoo saidI keep attracting guys that ask "Is this seat taken?" so they can take it to another table.
Oh gawd, so funny, so true! Nothing in the world worse than sitting alone at a cocktail table, and people start taking your other chairs away. Pretty soon it's you, the table, and the chair you're sitting on yourself, making you look all the lonelier, all the less likely to attract a guy, with no chair to offer him.
BTW, when somebody goes to take a chair I answer "That's for a friend I'm expecting." And if he never shows up, well, I guess he had a change of plans, can't blame me if he's unreliable, right?
