Questions & Answers about Мало того что я забыл проездной дома, так ещё и телефон разрядился.
It is an emphatic structure used to pile one problem on top of another.
A natural English equivalent is something like:
- It wasn’t enough that ...; on top of that ...
- As if ... weren’t bad enough, ... too
- Not only ..., but ... as well (but with more emotion)
So this sentence does not just list two facts. It sounds like a complaint: one bad thing happened, and then another bad thing happened too.
Here так is part of the larger pattern мало того что ..., так ещё и .... It helps introduce the second, additional problem.
By itself, так often means so, thus, or like this, but in this construction it is not really translated word-for-word. It mainly strengthens the connection:
- мало того что ... = it’s bad enough that ...
- так ещё и ... = and on top of that ...
You will sometimes hear shorter versions without так, but with так the pattern sounds very natural and emphatic.
