I feel you on the little things that make us say "Yes!" or "No!" on first dates. I've discarded people for reasons I regret ("wearing high heels") and ones I'm good with ("polyamorous"). Smoking is a toughie. I could tolerate "occasionally" like my brother who smokes maybe once a year if someone breaks out Cuban cigars. Toe nails? Teachable! Baldness? We all have shallow preferences. I think that's okay, as long as you don't weigh them higher than inner qualities. Marie Kondo would say move on. It's a tough call on whether a 2nd chance beats a new random date. (:
