Refusing To Serve Someone

Tonight was one of those nights where every customer seemed to want more than just a drink. They wanted attention, drama. And then there he was, this guy I knew from way back in high school, but we never really clicked. He’s been trying to hit on me for months now at other bars around town, even after I've made it clear I'm not interested. So tonight when he walked in the door, I rolled my eyes and went over to his table as usual. But instead of my normal polite routine, I just looked him straight in the eye and said, 'You're welcome here to drink, but keep your hands off me.' And then I turned around without a second thought. A few minutes later, he came up to the bar again. This time I told him point-blank: 'No more drinks for you tonight.' He tried giving me attitude back, but there was no way I was backing down. Do you think it's ever okay to make someone feel uncomfortable just because they're trying to date you?
