Yes? So... what happens with two withdraws in different offices? I know how it worked around 40 and 30 years ago, a little around 20, and there were some operations that were eventually consistent, like checks, but, specially several decades ago, they asked you to go to your office for certain operations.

Thinking more about it, and about the types of errors (the system got frozen and trying again duplicated entries), it remembers me a lot of how online selling worked 20 years ago. So probably they used the same patterns.

But I am really surprised. So, they are basically using DDD nowadays?
