Always someone at hand to help
Depending on where you touch down in the world culture and laws may be different. However what is a quite common general, is that the staff which you encounter is greatly helpful and knowledgeable.
If you have any issues at all the closest person you call on will usually have either the facility to help you straight away or at least have a good idea of where you need to go to get your issue resolved.
Staff meeting so many customers in one day, from such vast and varied background do become generally more understanding of the practical matters which need efficient solutions.
