I will never understand when a celeb responds to an obnoxious fan.  Why even waste your time on them?! Grant Hill was spotted at a gas station in Orlando this week  by an aggy Magic fan. The fan took a picture of Grant and posted it to his Instagram with a bitter message.  I have NO idea how Grant saw it (he wasn’t tagged), but he did AND he commented on it!!  The fan of course responded back — but he still just took an L. Lmao.  Check it out…
