Wtf is this kind of autism? Of course you got rejected but not primarily for your face
a. If you are so drunk that you are stumbeling and having gaps in your memory, it is really offputting to femoids (unless they are equally drunk). That's the dilemna of alcohol: Lowers the inhibition, but if you have drunk enough to approach women, they can't deal with your alcohol levels.
b. You can't just asc for her number a few seconds after you approached her (or in this case bumped into her), rejection is almost guaranteed if you do that. Maybe that works for 10/10 gigachad, but even chadlite and normie have to do conversation/flirting game first. Not that I know how to do that, but it is necessary.
You have the low inhibition that is needed, I guess you gonna get laid eventually
