No doubt sometimes the language can be a bit challenging.
But, overall (high percentage of the time over many years) I have been able to accomplish the necessary communication (often with a good laugh from both sides).
Much of it is on attitude combined with patience and appropriate body language. Throw in some respect and willingness to be flexible and BINGO.
Communication is a wide combination of things. It also is something that is more natural for some people than others. Also, circumstances can be a significant factor, ranging from a simple friendly gesture to mass chaos.
