A Commonality that the hospitality and tourism businesses usually share when it comes to structures or challenges is C. <em>They must create a pleasing atmosphere.</em>
- A pleasing and attractive atmosphere is the standard requirement for any entity that is engaged in hospitality or tourism.
- Clients put extra premium on the general pleasant atmosphere of the entity when they come visiting.
- Importantly, tourism relies on the hospitality industry to thrive in the same way that the hospitality industry encourages tourism to increase patronage and revenue.
Thus, both businesses complement each other and share a commonality of providing a pleasing atmosphere.
