Wifi

Im a regular customer of this place, the last time I was here I asked for wifi password I was told I must buy a meal before the password can be given to me,I visit here three times a week spend over R300 sometimes more with friends on just drinks now what really upsets me just half an hour after I left someone was given the password without even eating a meal, it gets interesting because the person that got the password was white and was even assisted by management to connect, my question, is this standard ? If so perhaps a sign should be put up (Wifi for certain people or wifi when you order ) came through today was told the samething
