Dealing with people in the most polite and basic way is also desirable as many of the local transport providers will not be speaking a language that is foreign to them.
Money is perhaps one of the biggest parts of travelling too, knowing the local currency is an essential skill. There have been moments where I have made mistakes in giving out extra money or sometimes too little. In some cases this can be taken advantage of and it is best to learn the basic numbering system, especially when going to a place where bartering might be in play. After a few weeks of studying I normally end up picking up a decent amount of number related linguistics. Handling the currency can also be a challenge and it would be wise to familiarise oneself with the various notes and coins available beforehand.
