Bad day in office

So, today I'm at this gig I landed for the weekend, an activation for Tusker. The gig is at machakos county. There is this game going on between tusker fc vs Gor mahia. It's 1-1 at the 87th minute, then tusker scores. Gor mahia fans all go wild. Because I'm activating for tusker, I'm wearing Tusker branded T-shirt. I've just received an order from a customer and some guys tell me " kama unajipenda Rudi mahali umetoka". Then naona beshte yangu ameinuliwa na mafans wa Gor anapigwa. We run to some washrooms nearby to hide, mind you ata hatuna nguo za kuchange.

Wameiba pombe, wameharibu machine ya Tusker, na wameumiza colleague kwa hii gig. Bossy amejam but hakuna kitu tungefanya.

Why are Gor fans like this?
