you can find this people at any buffet restaurant

this picture might give an idea on what is the main idea of my post for this time.

ah yes, its about eating. not food, but people who eat. there are few group of people respective to their criteria. this people are belong to each group because of their ability to eat. here we go!

the high roller
this people are the buffet high roller. they can eat, non stop, wayyyyy above avarage. this kind of people are not favoured by the buffet owner. because they can simply finish everything

the sweeper
normally in a group of 5. there would a person who would clean the leftovers. you see, in a buffet restaurant, the leftovers would have extra charges. Sweepers aims to finish what other can't finish. "garbage can" is too overated. like, you should be thankfull to them, because if not, extra charges on the bill!

normal player
normal eating ability, who would always make the worse day for the sweeper.

the extra large
they can eat a very large amount in a short time. they can eat, but they can't stop. if they stop, they'll be kenyang.

the slowpokes
they can eat, but takes a lots of time. few pauses through out the eating session.

a perfect formation:
in a group of 10 people, you might want to prepare for 2 Sweepers, 1 High Roller, 1 Slow Pokes, 1 Extra Large, and other normal player.
2 sweepers = sometime high roller do get exhausted. They are needed to clean everything up. they'll start eating a bit late than others,
1 slowpoke = atleast the sweepers has the third man.
1 extra large = start a bit in the middle, after everyone including the sweeper already started.
1 high roller = do what he do best
5 normal player = those people who kindly would contribute in filling up the table with foods which later they'll find it hard to finish.

LOL! :D
