I’m talking about physical attraction, without knowing anything about you. People will overlook many things if you are conventionally attractive and they have butterflies just looking at you, lust they call it. Ordering at a kiosk instead of a register is absolutely nothing to do with confidence though, it is a poor example of confidence. The OP is really clutching at straws if he thinks that’s a reason girls won’t date someone who stutters, and a classic example of a stutterer way over thinking it.
