Work over 60

After landing my new job as a Bunnings greeter, a good find for many retirees, I lasted less than a day. Why?
About two hours into my first day on the job a very loud, unattractive, mean-acting woman walked into the store with her two kids, yelling obscenities at them all the way through the entrance.

As I had been instructed, I said pleasantly,
'Good morning and welcome to Bunnings, nice children you have there, are they twins?'

The ugly woman stopped yelling long enough to say,
'Hell no, they ain't twins, the oldest one's 9, and the other one's 7!
Why the hell would you think they're twins? Are you blind, or just stupid?'

So I replied,
'I'm neither blind nor stupid, Ma'am, I just couldn't believe someone shagged you twice..?
Have a good day and thank you for shopping at Bunning?s.'?

My supervisor said I probably wasn't cut out for this line of work

Very good !!
I think your supervisor was right ... you should have been a stand up comedian
