Buzz-me is a very popular deejay, but experienced a steep decline in business during the Covid-19 pandemic, due to the Government's prohibition on gatherings for long periods. When the prohibitions were lifted, Buzz-me accepted all the offers they received to perform for months in advance. Amongst others, Buzz-me accepted an offer to perform as a deejay at Vusu's wedding on 10 September. On 16 August, Buzz-me heard that Shoe-kick, another very popular deejay, was in a serious car accident and would not be able to perform for a while. Buzz-me immediately contacted the organisers of the Yee-ha festival, enquiring whether Buzz-me can perform in the spot reserved for Shoe-kick during their festival on 10 September. Buzz-me was overjoyed when the organisers confirmed that Buzz-me was accepted to perform at the Yee-Ha festival on 10 September. On 20 August, Buzz-me remembers about Vusu's wedding and informs Vusu that they will not be able to perform at the wedding. Vusu is distraught, since they will not be able to find another popular deejay to perform at their wedding at such short notice.
