Why is there 丼 {どんぶり} in 丼勘定 {どんぶりかんじょう}?


How does 丼勘定 {どんぶりかんじょう} (sloppy accounting) related to 丼 {どんぶり} (bowl of rice
with toppings)? I mean, why どんぶり of all foods and things? Was there special
history for the origin of this set phrase?




Judging by the following link, どんぶり in this phrase didn't originally refer to
the bowl, but a pocket in the front of an apron, where money was kept:

If someone was throwing all the incoming money into one pocket and fishing out
change for customers from same, they probably didn't have a great idea at any
one time of how much they had or any way of keeping track.

style "どんぶり" for a little visual reference (you'll note they use どんぶり勘定 with
the hiragana).
