WHY MEN DUMB

Yesterday I was in my old job, because my GF couldn't go to work so I go for her. First a drunk guy came and asked about my instagram and because I didn't want to have anything to do with him and I was afraid that he would beat me up, I told him that I don't have an instagram. Then he asked for snapchat and since I wanted him to go away I told him I could give it to him and I would add him after work, knowing that I absolutely would not do that. Then before I could say anything more he said I wasn't his type anyway and left. Good for me but why the fuck are you bothering me?! When I was almost closing, a Spaniard came who didn't speak English and his friend had to explain everything to him. And the one who didn't speak English first asked in sign language if I wanted to have a threesome with him and his friend, and then asked in sign language again if I would suck him off. Holy shit, a random girl has never asked me a question like that, why do men think they can and then they're surprised when I refuse?! THAT IS DISGUSTING
