再比如，如果你迟到了，老板可能会生气。
总之，这个语法强调了一种因果关系，一旦某种情况发生，就会带来不好的结果。

The grammar pattern "~ばそれまでだ" or "~たらそれまでだ" is used to express a consequence or result that is inevitable or final.
It can be translated as "if that happens, it's all over" or "if that's the case, then it's the end.
" This pattern is often used to convey a sense of resignation or acceptance of an unavoidable outcome.
For example, if someone says "遅刻したらそれまでだ" (Chikoku shitara sore made da), it means "If I'm late, then it's over" or "If I'm late, there's nothing I can do about it", indicating that being late will lead to a negative consequence that cannot be avoided.
