A bus ticket is something "that confers value or benefit to its owners".

That's not what capital means. The bus ticket is an everyday expense that doesn't bring you anything by itself long term, you stop owning it as soon as you use it. Otherwise food would be capital too and the word would become useless.

Thought experiment: why is a one month software license to operate a conveyor belt to move product stock considered productive capital, but not a one month license for the employee to ride to the product stock. Indeed in at least one city I lived in, the taxes were deducted from my transit pass as the state counted it as a capital expense for my employment (technically the pass was not supposed to be used for anything else, but no one is checking).

In the grim thought slavery still existed, I would say food would be considered productive capital. In modern day (from the view of the company) that value is just captured in the wage so it would be inappropriate to double account it into capital expenses (a business lunch I think would count though).

Software licenses are not considered capital; they’re expenses. This is why they’re preferred for tax reasons, as expenses are fully written off in the first year, but capital purchases are gradually depreciated.

In that situation, food would still be an expense. The capital would be the slaves. Weird example though.
