that auction is going up small amounts because of auto bid not becuase he is nickle and diming. if he places a 500dollar bid and 50 people put smaller bids you will see the high bid, his high bid go up by small amounts.
some people also get upset if they get outbid by 50cents. you may get outbid by 50 at the end but their max bid may have been 50 buck more than yours so if you bid anouther 49.99 you would have been outbid by a penny.
