>Saw really tall (like 1,90m) grille at the store but didn't manage to talk to her
I saw a petite (165cm and slim) woman struggling to carry two packet bags that looked heavy. There was quite a lot of people around us, so I though I wouldn't appear as a creep if I come near her (I was walking behind her) and offer my help. And so I gathered my courage and did it. She said "no" though. So I changed course and entered a store nearby, so I wouldn't have to walk near her in the same direction; that would've been a bit awkward.
Wasn't today though, but a week ago.
