Should I pack money when traveling with my leaders?

Traveling with the leader should definitely not take all the money. If you make strategies and routes, book hotels and the like, you can do it well as a subordinate. But in terms of expenses, a little more enlightened leaders will remind you that invoicing can be reimbursed and so on.

If you don't mention this at all, as a subordinate, don't try to be brave and spend all your travel expenses by yourself.

First: your income is not as high as that of the leader, so there is no need to compromise your purse in order to please the leader.

Second: in fact, you spent money on the leader. Do you think the leader will appreciate you? He will only think that you are stupid and have a little self-knowledge, and will directly or indirectly propose how to share the toll.

Third: if you travel at public expense, it goes without saying that you can reimburse it. If you are traveling privately with a leading organization, it should be AA.
