Lolly Jar Etiquette

At the moment I am doing some extra work at nights for a group I can't name but lets just say that they are sometimes referred to as being "bored of studies" in a part of Australia that is sometimes compared to the south of Wales. Anyway... it is tradition at these sessions that a lolly jar is passed around each group and that each member of the group contribute at some stage. Snakes, jelly beans, minties, whatever, you get the idea. However over the years I have come across some people who break lolly jar etiquette! And there happens to be two such people in my group this year!
Offender Number 1: Lets call him Selfish Overcomb Guy (SOG). So whenever SOG gets the lolly jar passed to his table he firstly pretends that he doesn't know its there. However, every so often he eats a lolly. Now this would be ok if only done for 10 or 20 minutes, but SOG had the lolly jar on his table for 1 and 1/2 hours helping himself every 5 minutes of so!!! People started getting up and going over to his table just to get a lolly, but he still didn't catch on!! Eventually i got up to get a lolly and said to him "how about I pass these around?" to which he replied, "yes well, they aren't mine anyway." It was all I could do to not point out the irony.
Offender Number 2: Lets call her "Heart of Ice" (HOI). Anway I first met HOI last year and she hasn't changed. She also is a serial non-passer of the lolly jar, but unlike SOG she never eats a lolly. However she does act extremely annoyed whenever the jar comes her way. I dont just mean slightly annoyed I'm talking someone just ran over her foot with a 4WD annoyed! She gives a look as if to say, "Do I really need to go to the effort of passing this thing on again." Is it really that hard HOI?? No, no it isn't. Look I'm not expecting HOI to drop everything to pass on the lolly jar, but maybe after its been on her desk for 20 or 30 minutes it wouldn't be too much effort!?
