Buffet etiquette ... I've often wondered if buffet restraunts should just post a sign at the head of the line outlining this.It's interesting because they charge an adult rate and a kids rate; the kids rate is based on age (so much per year). There are items there tin the latter afternoon that are not part of the "lunch buffet" but they are marked as such (they cost extra.... mostly the pricier seafood). I go there with my kids maybe once a month and I'm very strict with them that they do not take anything unless the eat it, and that does not include multiple trips to the desert buffet.
We also occasionally eat at a buffet who prices children according to age, has a senior citizen discount and all adults are charged the same, regardless of how much or what they take. "All you can eat" means "all you can eat" unless they specify otherwise.
However, my kids abide by the scout rules: Take half as much as you think you can eat on your first trip. After you finish that plate and your drink, if you still find yourself *hungry* then you may go back for more - and only one trip to the dessert bar.
But again, this is voluntary behavior - it hasn't been asked of us and we could certainly make a dozen trips to the buffet as we pleased ... there's no sign limiting us.
