Fishing one at a time can be time consuming as well.
Besides, if you're already seeing a WL regularly without her banning you or purposely cancelling your bookings constantly, she's pretty much already into you.
I remember being the fish for my crush. She may think she lured me in but I was the one who jumped straight into her Esky. I was like a stray cat who chanced at picking a human who would feed and love her rather than get kicked out into the streets.
