British worker files discrimination lawsuit after being called a ‘gweilo’

Interesting. See it isn't only Caucasians who discriminate.

the company is lucky their blasting specialist didn't decide to do some extraneous blasting

Sure, this individual might be motivated by self-pity. Without knowing the full story, it's hard to make that call. If he was the expert and they were bypassing him, it may have been due to discrimination - or it may have been due to corner-cutting the company didn't want him to know about. Hurt ego or safety violations? My wings were not for jumping to conclusions.
