Declarations

:

: This study was approved by the ethics committee of the University of Dodoma. The participants provided verbal consent. The committee approved this approach, and verbal consent was deemed appropriate because respondents were obtained from restaurants or hotels when they received services, and hence, it was difficult or impossible to provide written consent. In addition, anonymity was highly considered, and hence, written consent was not found to be necessary.

: Not applicable.
