Someone I consider a collegue but not friend giving me a gift card to a place I like instantly makes me think they value me more than I thought. Person I consider a friend gives me a gift card instead of a gift, depending on the occasion, makes me think they like me, but can’t be bothered to put too much effort in, or are just doing because they feel obligated.
