Why are our tradies like this?

Having some renovations done and these tradies and brickies come over to work. I'm a big cricket fan so I have lots of players jerseys from all around the world. And by my misfortune I had my kohli one on the hoist and also had my de viliers one too but they didnt notice that. And I overheard these guys go crazy about it, like

"brown fucking indian fucking hindu fucking c u n t, give me curry ding a ling a ling a ling."

I thought that was kinda funny, but then later on, these guys were farting and trying to see who had the smellier one. And that's when I noticed that our tradies are really weird (late to the party ik), and deduced that my house is 100% falling down a week later after they're finished.
