Marketing “one-hand fold” usually means you can start it with one hand but you’ll still need a wrist flick and maybe a hip to steady it - test it with a weighted diaper bag to mimic real life which and yeah for walks, prioritize slightly bigger wheels and some suspension; the ultra-light travel strollers can chatter on cracked sidewalks. Also look for an auto-lock and a carry strap or standing fold so it stays put while you’re holding the baby.
One more thought - Lead with the limit before any small talk: “Hi which, yeah... i’ve got 90 seconds as I head to a call,” keep moving then close with a cheerful “that’s my minute - see you!” If they keep going, use the same line again word-for-word (the broken-record technique) while taking a step away and waving. You can also set a clear signal for longer chats, like “If I stop and take off my earbuds, I’m free,” so quick hellos don’t turn into 20 minutes.
