More than 200 die at a night club in Rio Grande do Sul

[Vipershark]

If by dining you mean a place where people actually go for food, also no. It was most certainly a concert club or something of the sort.

Unless it's different there, here we don't pay right away. We get a standarized piece of paper which has everything you ate and drank marked down and then you pay later at the register, before leaving. Then you hand over this piece of paper while leaving. If you lose it, you have to pay a (quite big) fee to compensate.

Or I'm not getting what you mean at all

Ah, no wonder.

Here, you pay for a ticket to get in, then you can leave whenever. Food and drinks are bought and paid for at the bar.
...that way things like this don't happen.
