**12. Ethical issues**

The respondents were informed of the study's purpose and that their responses will be analysed and compiled into a report solely to fulfil the requirements of independent publication. Furthermore, the respondents were informed about their right to voluntary participation, the confidentiality in which their responses will be treated and the survey ensured their anonymity by not collecting identifying information such as names, surnames or photos. By completing and submitting a questionnaire, it was taken that the respondents have consented to the ethical considerations. Ethical clearance was sourced from Turfloop Research Ethics Committee (TREC) and the certificate (TREC No: TREC/221/2019: IR) was issued on 04 September 2019.
