When people who have a habit of giving expensive 'surprise' gifts get an attitude when you're not thrilled or exchange it.

They have a penchant for getting it wrong and buying things you don't want or need, or that are the wrong size or color, or are something you're allergic to. They're so pleased with themselves but only buy things they like rather than considering you personally, then blow up or sulk when it doesn't go over like they anticipated.
