Some men are oblivious to queues. However, they are rewarded many times over for that same creepy/annoying approach so there's no incentive to switch it up.
A lot of behaviors being pointed out in this thread are just straight up creepy , but the bolded is an interesting observation.
It brings to mind when some women will initially reject a guy's advances, but the guy is persistent about approaching her and she ends up becoming more receptive to him over time.
Outside of not being a straight up creep, there's no one-size-fits-all approach that works with all women, so a lot of dudes just end up using the shotgun approach
