Sometimes it paid to be blunt when I was divorced the first time and barely drinking age. I went out to bars wth live music several times per month. It got to where if a guy offered to buy me a drink, I'd look him in the eye and tell him, "Thanks, that would be fine as long as you know I am not going to f*** you for it." Most of them expressed relief that we'd gotten THAT question out of the way, even if it wasn't exactly what they were hoping for.We'd usually have a nice evening of dancing and talk, OR, they'd go try it on someone else. That was many years ago, pre-AIDS, but it did seem the prevalent implication, i.e. if a fellow bought a girl drinks, she would have sex with him. I do still favour upfront communication.
