Waiing remains to this day an extremely important part of social behavior among Thais, who are very sensitive to their self-perceived standing in society. Foreign tourists and other visitors unaccustomed to the intricacies of Thai language and culture should not wai someone younger than them except in return for their wai. However, one should always return a wai that is offered as a sign of respect. Corporate wais, such as those performed by convenience store cashiers, generally are reciprocated with a smile or a nod.
