Now if the person has an ulterior motive for gifting me which is to impress or win me over, then I'll politely decline such gifts while letting the person know that using gifts as a means to impress isn't really ideal and should be stopped forthwith

Awwwwwn! So there are still ladies like this?
The people I know, they'll chop the gift because it's a 'normal' thing and still reject the person 😎
