Had a buffet line of candy...

told them ..."You get 3 things, then you have to move on. You can come back and get another 3 things after everyone has been through the line"

YEP... it is SOOOO annoying to see people who are sooo completely self-absorbed and completely unaware of others that stand there forever making their plate perfect. At Ward Parties we also set up 6 lines, and I will say loudly to people "go ahead and come around over here, this line is moving quickly"

At youth activities we try to teach it ... Grab two things and move on. The youth kind of get it. Some of our adults just don't even recognize that they causing a problem.
