Hwang "et al." suggest that server disclosure is more effective to evoke customer disclosure in female customers, who are more likely to reveal personal information than their male counterparts. In addition, studies have shown that factors such as expertise (e.g. servers' knowledge and experience), customer-oriented attribute (e.g. listening to the concerns from the customers attentively), as well as marital status influence mutual disclosure in the restaurant setting. Expertise is positively correlated to both customer and server disclosure. Server disclosure is only effective in inducing disclosure and positive feelings from unmarried patrons who are more welcome to have a conversation with the servers.
