幹啥吃到跑？吃得太飽了，跑廁所！


=====================================================
我的胃腸是單一食物式的，最多只能容納兩種食物，同時吃下十幾種，我的胃腸就搞不清楚到底要分泌哪種消化液，一概送作肥料堆，直接排泄出腸。
 
吃到飽吸引人潮的誘因，不在於讓大食客撈本─絕對撈不了本，除非餓上一兩星期再去吃，恐怕到時頭昏眼花，胃腸縮小，啥也吃不下。雖然陳列的食物種類繁多，滿足的是眼睛和心情而已，光看就飽，真要下肚，一兩盤就結束了。　

吃到飽受歡迎的關鍵在於省去點餐麻煩，是各樣人類人渣人妖聚餐的最佳選擇──各自選擇要吃的，降低點錯餐被人埋怨的風險，對懶得動腦族來說，是不用選擇的選擇，讓挑剔鬼再也挑不出鬼。

後遺症:

1.人們的胃腸被弄壞
2.食物被大量浪費
3.動物冤枉被殺

All you can eat


Meaning

A restaurant advertising slogan (usually followed by a price).

Origin

It will probably come as no surprise that this is an American phrase. 

'All you can eat' restaurants spread throughout the USA during the depression years of the 1930s, when diners' hunger was often bigger than their budget. 

The deal with such restaurants is an unlimited amount of food, usually arranged as a self-service buffet and usually of pretty low quality, for a fixed price - also low. 

'All you can eat for $1' was a typical early slogan. 

The earliest example that I've found in print is an advert in which Penn State University appeared to be aiming to help out its students' budgets by publicising a cheap local eatery (小)飯館- in the Penn State Collegian, November, 1922.

A visual impression of such a restaurant from the 1930s comes in one of Harrison Cady's Peter Rabbit cartoons, published in the Oakland Tribune in April 1933.

'All you can eat' is still a popular form of dining and has now spread to all continents. In more recent years the restaurants have moved up-market somewhat. Minimum price is no longer the only factor and you aren't now likely to eat all you can for 50 cents or $1.

In the late 20th century the phrase began to be used in an allusory manner, that is, not limited to references to food. An example is from a 1994 edition of Internet World:

"Costs of typically $1-2 per hour or $10-$30 per month for 'all you can eat' use of reachable free-for-access Internet service."
