I'd just say it to them outright Jimmy. Just say "You know it's piss ignorant comments like that are what get people fired", say it sternly, and walk away. Let the retards think about it, they'll be much more inclined to keep their opinions to themselves if they know they're jobs are at risk. If it keeps up just write a letter to HR in your job and explain that your able to take a case up against your employers if they fail to act on it.
I on the other hand, am stressing out big time over money. I've a pain in my hoop with it. Had to spend 90 quid getting a passport today, then I've to spend another 20 on wednesday just to get binding for a poke bonnett, as well as lining and ribbon for it, which is going to cost me at least 50 more quid. I've also rent to pay, a bill to clear by the end of the month, and I've to pay one of my mates for booking my hotel room for my holiday in July (I could put that on the long finger but I'd hate if it was me on the other end waiting for friends to pay me back). The cat also needs to be neuteured because the bitch is in heat and keeps rubbing her arse against anything she can and meowing.
Realistically, if I stayed at home for the next two weeks and didn't bother going out, I'd still be behind schedule financially. Pain in the arse.
