Booked a street dancing class for the first ever time along with a friend. After taking extra efforts to cancel personal appointments to make up to this class, we find out that the instructor is on a holiday after arriving at the venue. We were so excited that we even arrived half hour early for the 8pm class. Being a professional dance studio you would imagine they would have these basic workflow organised. Appalling.
