There is one nationality that i know a lot of tradies have told me they wont deal with.
There painful and try to screw you down for every dollar when asked to quote or do any residential works.
And as they say to me no point upping the price for quotes with these people as a measure to deal with the drama because at the end of the day they come back with a billion questions anyway to screw you down from the original price.
Some can't be bothered good luck to those who want to deal with it.
Then you have to make sure you get the $$$ off them when the job is complete.
You can say it you know. It's not racist.
E.g. This true story. I was talking to a white Australian woman about 2 yrs ago at my local butcher. She had her 6 yr old daughter with her who had henna or hanna or whatever you call them brown temporary tattoos that the sub continental ladies like to adorn themselves with on the back of both hands.
I enquired about it and was informed that the daughter was the only non sub continental kid in her class and none of the sub continental girls wanted a bar of her.
In an attempt to fit in, the hands were done with Mummies assurances that things would improve. Over the 7 days the tatts had been on the daughter, there was no improvement from the attitude of her fellow class mates.
You then have to ask yourself how the f**k do 6 yr olds get to be like that?
I'm not sure about it but I have my suspicions.
I've deliberately used the term sub continental here as once you get past the white ones, discerning between an Indian or a Sri Lankan can be difficult even for this seasoned pro.
